Re: Mosrite 300 and 350 Serial Numbers? (Guitar and Bass)

Postby 101Volts » Fri May 21, 2021 7:25 am

Update for May 21, 2021:

Unknown Brown Bass (possibly AB0047) added.

Also, I've added a speculated # section to the 350 Bass section, and I removed the probable AB0032 from the Partial # section to the Speculated section.

Minor Update for May 20, 2021:

Minor update to A0344 added, to reduce confusion of "A0?44" being in the list.

Update for May 14, 2021:

Stereo 350 Bass AB0019 (Natural) added.

I also added info of which initials (E.W.) are on the fretboard, beneath K0005's number.

Other minor changes have been made, including a small model trivia section, for anyone who's unfamiliar with the differences between 300 and 350 models.

Legend:

An instrument new to the list (or moved from an Unknown section) as of the day the list is updated, whether the instrument has a number or not, will have Bold and Underscored Text for its Serial Number (or "unknown number") to stand out. (Examples: A0100 and A0xxx [Unknown 350 Guitar Example.]) When one of these marks is new, I'll also keep it in bold underscored text in the following update, but I'll remove the marks in the update after that.

Instruments that are finished in any kind except Natural, White or Yellow will have their finish set in colored text, except for Black. Black instruments will use Bold Text, to stand out more clearly.

Model Trivia:

300 models are 1-Pickup (in stock form) models. They came as Guitar and Bass. Few have shown up, though I don't think they'd be any more valuable than a 350 model in 2021.

350 models are 2-pickup models which came as Guitar and Bass. There are "Stereo" (2 cord output) and "Mono" (1 cord output) models of each Guitar and Bass, and it appears that Stereo models are more common than Mono models.

300 Models:

Basses - 4:

KB0002: Natural, 1 Neck Pup. Pic and page saved. Once owned by Michael Marks. I'm not sure if he still owns it. Found here: http://home.insightbb.com/~marksma/wsb/ ... 34980.html
KB0022: Brown, 1 Bridge Pup. Pics and page saved. Showed up on Reverb in February 2020. Listed by Hugo Helmer Music, Inc. https://reverb.com/item/32677431-mosrit ... arly-1970s
KB0048: Red Burst, 1 Bridge Pup.
https://hiveminer.com/Tags/70s%2Cmosrite
KB0063. Red, or Brown (maybe it's just an aged Red finish.) 1 Bridge Pup. Pic saved. Owned by Talkbass member blastoff, and he also bought another of these, Stereo Bass AB0036 (Blue.) KB0063 Number updated at the forum in Dec 2020. More photos downloaded, Jan 18, 2021. https://www.talkbass.com/threads/mosrit ... t-23820986


Partial Numbers Section - 0:

Guitars - 4:


K0005: Natural. Has 1 Stock Neck Pup. Pic saved. Also has initials, "E.W.," beneath the serial number. Owned by Alan Manoian, who also owns 350 Guitar A0150. http://www.mosriteforum.com/forum/viewtopic.php?t=357
K0006: Natural. Owned by forum member mosriteforever. Mentioned at the same link as K0005, above.
K0010: ? One probably stock humbucking pup at neck position, no bridge pup. Mentioned first here, by Moaimen: viewtopic.php?p=71576#p71576
K0016: ? Has a probably stock and slanted Neck Humbucker, and a Single Coil Bridge Pup (which was probably added later.) It has 2 knobs, 3 switches, and Mono wiring. Mentioned first here, by Moaimen: viewtopic.php?p=71576#p71576

Speculated # Section - 1 Guitar:

K0009: Natural. Pic saved. Vaguely appears to be K0009, but I can't tell for sure in the photo. Doesn't have its stock pickup installed at the moment. It has been drilled to have a Bridge Pickup, too. It has a Bill Lawrence pup in the Bridge, a Seymour Duncan P90 in the neck, and an extra knob. Owned by forum member "rtdreep," who has owned it since 1978 (roughly speaking.) He does have the stock pickup, though. The guitar was mentioned in the forum, here: viewtopic.php?f=4&t=7994

AB0036: Stereo, Blue. Photos and page saved. Has a Maple neck. Ad says the body's made of Alder. This finish may be original, since it looks old, and it looks like it aged like other 350s. This is the second Blue 350 I've seen; A0148 (a Guitar) is also Blue. https://reverb.com/item/34060236-mosrit ... blue-1970s Photos from 2016, before this instrument was for sale on Reverb, show this instrument without a Mosrite logo.

Speculated #s - 2:

AB0032: Stereo, Red. - Was on eBay Australia in March 2010, for sale by seller "waitebt." This is likely to be AB0032, but I can't make out the A, or the first digit after the B.
AB0047: Stereo, Brown. I'm not sure of the 4 that I read, but I'm more confident that there's a 7 at the end. - 2 Piece Neck. Pic and page saved. http://www.oldfrets.com/Mosrite.html

No # - 1:

AB0xxx: Stereo, Lemon Yellow/Aged White Finish. Was on eBay in February 2011. Pics saved. Doesn't have Mosrite M Knobs (just like A0345 which is also Yellow,) and it appears that Mosrite used cheaper knobs late in the model run.
viewtopic.php?f=27&t=4063
AB0xxx: Stereo, White. Has the Radio Shack-type Knobs on it. I expect this is a late one. Shown in this Youtube video from user "Rusted Vacuum," but the bass was not played in the video: https://www.youtube.com/watch?v=ISR68ErQ_L8

A0148: Mono, Blue and 5 M Knobs (?) Also, it has a Fender Bridge on it. Pics and page saved. The page claimed this guitar was used by The B-52s, but no link's provided to this claimed video. Maybe he meant the brand was used by The B-52s? https://www.stubblebinelutherie.com/gui ... n-ink-blue
A0150: Mono, Brown (Not "Brown Burst." Has a faint gold hue if you look at it right.) Pic saved. Bought by Alan Manoian on eBay in 2004 or so. He also owns 300 Guitar #5. Thanks for sharing the number.

A0207, ?, Natural. I posted it years ago:
viewtopic.php?f=27&t=6115
A0217: Stereo, Natural. Was on eBay in June, 2010.
A0223: Stereo, Natural. Doesn't have "M" Knobs. Listed on Reverb by Mike and Mikes Guitar Bar on October 5, 2019. Neck Humbucker says 10 - 8 - 73.
https://reverb.com/item/28494243-1973-m ... ckers-case
A0227: Stereo, Natural. Doesn't have Mosrite "M" Knobs. Listing ended in April 2012. Number is according to auction description. https://www.liveauctioneers.com/item/11 ... solid-body
A0232: Stereo, Natural - Ended on eBay October 13 2018.
A0237, Stereo, Black. I posted it at the forum in February 2014:

A0238 - Stereo, Natural. Has M Knobs. Once owned by Michael Marks; I'm not sure if he still owns it. http://home.insightbb.com/~marksma/wsb/ ... ip-15.html

A0270, Stereo, Brown Burst. Showed up on Reverb on May 20, 2018 from SRM Music.
https://reverb.com/item/12271768-mosrit ... rown-burst
A0271, Stereo, Brown Burst. Pics and page archived. Sold by "hammondguy" on eBay on October 29, 2020 for $1,195. Has been refretted, and the zero fret is now stainless.
A0293, Stereo, Red Burst. Pics saved. A clear photo of it was posted on Facebook from "Blues Rock" in Hong Kong, and I saved the photo. This is highly likely to be the guitar I linked in the Reverb ad; the wood matches up. If it is the same guitar, they bought it without M Knobs, and added M Knobs later (which may or may not be accurate to how it was originally sold.) The older Reverb photos are barely legible, but I made out that they seemed to be A025? or A029?, judging by the closer photo. Reverb ad:
https://reverb.com/price-guide/guide/24 ... 0-1974-red
A0309, Stereo, "Walnut Burst" (probably a Brown Burst.) Had a nut instead of a metal string guide when it showed up in February 2014. I posted it years ago: viewtopic.php?f=27&t=6118
A0329, Stereo, Black. Has M Knobs, and has a Bigsby added. Once owned by Michael Marks. http://home.insightbb.com/~marksma/wsb/ ... 63768.html
A0331, Stereo, Black, Owned by Forum Member In-stereo.
A0344, Stereo, Black. Nate Gibson's Guitar. Pics saved. Has been customized and repaired, and it has M Knobs. The pinstriping on it was done by Charlie Decker, the Armrest and Pickguard by Sarah here on the forum, and Evan Williamson worked on the crumbling binding. Also, I saved a photo of what's probably it, pre-customization, from Eastwood Guitars' site. I tried, and I was then able to make out the numbers as being "A0?44:" https://eastwoodcustoms.com/projects/mosrite-350/
A0345, Stereo, Yellow. Pics and page saved. Knobs are teardrop shaped. Listed on Reverb by Poway Jewelry and Loanon September 20, 2019. https://reverb.com/item/28163955-vintag ... ric-guitar
A0349: Stereo. Natural. Knobs are Plastic, probably original. Sold by "Big Brothers Pawn Springdale" in
Springdale, AR, United States. Price: $1,100 + $150 shipping. https://reverb.com/item/39740038-mosrit ... s-mahogany
A0350: Stereo. Black or Forest Green. Pics saved. A seller called this finish "Forest Green." Owned by forum member GTSP (as noted in the second link below.) Photos saved from his Photobucket page. It looks Black instead of Green to me, but maybe it's just the lighting in Jayson's photos, since I vaguely remember this guitar being green. Serial # is according to Jayson. Thanks for sharing the number.

A0365, Stereo, Red Burst. Has M Knobs. Pics and pages saved. Once owned by Michael Marks; he sold it. http://home.insightbb.com/~marksma/wsb/ ... ip-15.html

Partial #s Section - 1:

A002x, Stereo, Natural Finish
http://www.mylespaul.com/threads/1970-m ... er.301797/

Partsrite Section - 1:

No-Number Partsrite, Mono, Red - Pics and page saved. Has a Sooner neck, and it says "Super 350" on the headstock. Has one Volume Knob, and one Tone Knob. It has two unknown switches, near the Vol and Tone Knobs. It also has a Black Widow-sized pad on the back, which is on other instruments of Tony Hunt's.
https://www.liveauctioneers.com/item/97 ... -with-case

Speculated # Section - 5 Guitars

Numbers in this section are as close as I could speculate, after looking at photos or by other speculation.

A0006? Stereo. "Light colored body wood." Seller gave number as "9000 V," which I suppose could have been read upside down. This is not confirmed, though. First mentioned here, by moaimen: viewtopic.php?p=71576#p71576
A0038: Stereo, Natural, stock. Belongs to Tim Brennan. Can be seen at his Facebook post, here: https://www.facebook.com/Tymguitars/pos ... 0711924953
A013x or A015x: Mono, Red. Has a Moseley Vibrato. May be A0134, but I can't tell very clearly.
https://www.sheltonsguitars.com/2008/1- ... 08-08.html
A0291: Stereo, Brown Burst. It seems most likely to be A0291, judging from other Brown Burst guitars near this number and by how the 9 stamp appears on other guitars. This guitar has a Nut instead of its original String Guide. This is the guitar photographed on the side of this page, under the description for the 350 model:
https://reverb.com/p/mosrite-stereo-350-sunburst-1972
A0304: Stereo, "Bright" Sunburst (compared to the brown ones.) Appears to be A0304, but it's hard to tell. Knobs aren't the "M" type (but are possibly original.) Was apparently for sale from Detroit Guitar, since it's posted to their Pinterest page. https://www.pinterest.com/pin/552605816757739103/

Unknown #s - 13:

A0xxx: Stereo. Black. Owned by Lil' Jimmy Reed, and is customized; has "Lil' Reed" on the body and headstock. It may be somewhere over A0300, judging by the numbers of known Black 350s. Video from 2013: https://youtu.be/ZYc0CtwvItQ
A0xxx: Stereo, Brown. Was for sale on eBay on March 24, 2011. Photos have been saved.
A0xxx: Stereo, Dark Blue. Has M Knobs. Pic saved. Pic shared by Charley Johnson on Facebook. This is the third Blue 350 I've seen. I'm not sure if it's original, or refinished.
A0xxx: Stereo, Natural. Doesn't have M Knobs. Pic saved. Body was heavily cut away to look more teardrop-ish. Found on Facebook, posted by Larry's Guitars. I think I can still see at least one number on it, but I can't quite tell what it is.
A0xxx: Stereo, Natural. Appears to be in the first 100, but I can't tell for sure if it's A0057, A0067, A0069 or A0075. Appeared in late 2020, from Jean-sebastien's saucisserie shop in Baie Des Sables, Canada.: https://reverb.com/item/37253942-mosrit ... -week-deal
A0xxx: Stereo, Brown Burst.. Pic saved. I found the photo on Pinterest, and followed the link; it was down. I found the original ad in the Wayback Machine, but most of the photos weren't saved.

Tym Brennan's Unknown # 350s;
A0xxx: Mono, Natural. Has a Mosrite Single Coil in the bridge.
A0xxx: Mono, Dark Sunburst. Has a Maple Ventures neck, a Mosrite single coil in the neck position, and a Mosrite stop-tailpiece screwed into a Moseley Vibrato Base Plate with a stoptail screwed through it. I question why the baseplate's installed.

All of Tym's 350s can be seen here:

May not have a # anymore:

A0xxx: Stereo, Natural. Pics saved. Doesn't have M Knobs. Has a Bigsby and a Tune O Matic, and was refretted twice (so it may no longer have a number.) Found on Facebook, posted by William R. Crabtree.
A0xxx: Stereo, Natural (or slightly more brown.) May have lost its # in a Refret (judging from photos) though I'm not certain if it did lose the #. Formerly owned by Will Speer (Will S on the forum) and was played in a 2007/2008 video from Rockongoodpeople. viewtopic.php?f=6&t=1942&p=19381#p19381
https://www.youtube.com/watch?v=HCvTLZ8R-2Q

--------------

94 instruments are listed (or fewer, due to the unknown and speculation sections.) 1 350 Stereo Bass, AB0019, added in this update.

4 300 Basses,
4 300 Guitars,

1 Speculated # 300 Guitar
1 Partial # 300 Bass,

1 No Number 350 Bass,
9 350 Basses,
2 Speculated # 350 Basses,

47 350 Guitars - 11 or 12 Mono, 35 or 36 Stereo.

1 350 Guitar with a partial #,
5 350 Guitars with speculated #s,
1 Guitar that's a Partsrite,

6 Unknown 350 Basses
13 Unknown 350 Guitars.

Finishes Accounted For:

Black - Shows up late in the model run. (Earliest known guitar is A0237, though I wonder if it's really 337, and the earliest bass is AB117 - which happens to currently be the highest # for a Stereo 350 Bass.)
Blue - 3 accounted for.
Brown.
Brown Burst.
Natural - This is the most common finish seen. About the first 60 seem to be Natural, though without each one individually accounted for, I can't say that for certain.
Red.
Red, Translucent. (A0065.)
Red Burst.
Sunburst - 1 accounted for, though it may not be an original finish. The guitar is a speculated (but highly likely to be) A0304.
Yellow - 2 accounted for. (1 mystery bass, and Guitar A0345.) Perhaps these are the only 2, and they were ordered at the same time.
White - 1 mystery # bass accounted for.

Also, Guitar A0350 was once described as "Forest Green," in the ad where forum member "GTSP" bought it. I'm not sure if it's really a Dark Green, or a Black finish.

I feel confident that the Black, Brown, Brown Burst, Red, and Red Burst instruments are all original finishes. The Yellow ones might also be original, since I've found two of them that look nearly the same.

I'm not so sure about the originality of the Blue ones, the Green/Black one, or the White one. If I had better pics of the Unknown # Blue one, I could more easily tell.

And now, here's the Photo for Facebook:

Re: Mosrite 300 and 350 Serial Numbers? (Guitar and Bass)

Postby 101Volts » Sun May 23, 2021 4:24 am

Update for May 23, 2021:

More info to the Red Partsrite "Super 350" Guitar added.

Also changed the speculated Red Guitar with a Mosley Tailpiece to "A0134 or A0154," instead of "A013x or A015x." I can't tell the last digit very well, but it seems to be a 4, and it's in the speculated # section anyway.

Update for May 21, 2021:

Unknown Brown Bass (possibly AB0047) added.

Also, I've added a speculated # section to the 350 Bass section, and I removed the probable AB0032 from the Partial # section to the Speculated section.

Legend:

An instrument new to the list (or moved from an Unknown section) as of the day the list is updated, whether the instrument has a number or not, will have Bold and Underscored Text for its Serial Number (or "unknown number") to stand out. (Examples: A0100 and A0xxx [Unknown 350 Guitar Example.]) When one of these marks is new, I'll also keep it in bold underscored text in the following update, but I'll remove the marks in the update after that.

Instruments that are finished in any kind except Natural, White or Yellow will have their finish set in colored text, except for Black. Black instruments will use Bold Text, to stand out more clearly.

Model Trivia:

300 models are 1-Pickup (in stock form) models. They came as Guitar and Bass. Few have shown up, though I don't think they'd be any more valuable than a 350 model in 2021.

350 models are 2-pickup models which came as Guitar and Bass. There are "Stereo" (2 cord output) and "Mono" (1 cord output) models of each Guitar and Bass, and it appears that Stereo models are more common than Mono models.

Speculated # Section - 1 Guitar:

K0009: Natural. Pic saved. Vaguely appears to be K0009, but I can't tell for sure in the photo. Doesn't have its stock pickup installed at the moment. It has been drilled to have a Bridge Pickup, too. It has a Bill Lawrence pup in the Bridge, a Seymour Duncan P90 in the neck, and an extra knob. Owned by forum member "rtdreep," who has owned it since 1978 (roughly speaking.) He does have the stock pickup, though. The guitar was mentioned in the forum, here: viewtopic.php?f=4&t=7994

AB0036: Stereo, Blue. Photos and page saved. Has a Maple neck. Ad says the body's made of Alder. This finish may be original, since it looks old, and it looks like it aged like other 350s. This is the second Blue 350 I've seen; A0148 (a Guitar) is also Blue. https://reverb.com/item/34060236-mosrit ... blue-1970s Photos from 2016, before this instrument was for sale on Reverb, show this instrument without a Mosrite logo.

Speculated #s - 2:

AB0032: Stereo, Red. - Was on eBay Australia in March 2010, for sale by seller "waitebt." This is likely to be AB0032, but I can't make out the A, or the first digit after the B.

AB0xxx: Stereo, Lemon Yellow/Aged White Finish. Was on eBay in February 2011. Pics saved. Doesn't have Mosrite M Knobs (just like A0345 which is also Yellow,) and it appears that Mosrite used cheaper knobs late in the model run.

A0271, Stereo, Brown Burst. Pics and page archived. Sold by "hammondguy" on eBay on October 29, 2020 for $1,195. Has been refretted, and the zero fret is now stainless.
A0293, Stereo, Red Burst. Pics saved. A clear photo of it was posted on Facebook from "Blues Rock" in Hong Kong, and I saved the photo. This is highly likely to be the guitar I linked in the Reverb ad; the wood matches up. If it is the same guitar, they bought it without M Knobs, and added M Knobs later (which may or may not be accurate to how it was originally sold.) The older Reverb photos are barely legible, but I made out that they seemed to be A025? or A029?, judging by the closer photo. Reverb ad:
https://reverb.com/price-guide/guide/24 ... 0-1974-red
A0309, Stereo, "Walnut Burst" (probably a Brown Burst.) Had a nut instead of a metal string guide when it showed up in February 2014. I posted it years ago: viewtopic.php?f=27&t=6118
A0329, Stereo, Black. Has M Knobs, and has a Bigsby added. Once owned by Michael Marks. http://home.insightbb.com/~marksma/wsb/ ... 63768.html
A0331, Stereo, Black, Owned by Forum Member In-stereo.
A0344, Stereo, Black. Nate Gibson's Guitar. Pics saved. Has been customized and repaired, and it has M Knobs. The pinstriping on it was done by Charlie Decker, the Armrest and Pickguard by Sarah here on the forum, and Evan Williamson worked on the crumbling binding. Also, I saved a photo of what's probably it, pre-customization, from Eastwood Guitars' site. I tried, and I was then able to make out the numbers as being "A0?44:" https://eastwoodcustoms.com/projects/mosrite-350/
A0345, Stereo, Yellow. Pics and page saved. Knobs are teardrop shaped. Listed on Reverb by Poway Jewelry and Loanon September 20, 2019. https://reverb.com/item/28163955-vintag ... ric-guitar

A0350: Stereo. Black or Forest Green. Pics saved. A seller called this finish "Forest Green." Owned by forum member GTSP (as noted in the second link below.) Photos saved from his Photobucket page. It looks Black instead of Green to me, but maybe it's just the lighting in Jayson's photos, since I vaguely remember this guitar being green. Serial # is according to Jayson. Thanks for sharing the number.

It also has a Black Widow-sized pad on the back, which is on other instruments of Tony Hunt's. Currently owned by Pete Kenney.

Speculated # Section - 5 Guitars

Numbers in this section are as close as I could speculate, after looking at photos or by other speculation.

A0006? Stereo. "Light colored body wood." Seller gave number as "9000 V," which I suppose could have been read upside down. This is not confirmed, though. First mentioned here, by moaimen: viewtopic.php?p=71576#p71576
A0038: Stereo, Natural, stock. Belongs to Tim Brennan. Can be seen at his Facebook post, here: https://www.facebook.com/Tymguitars/pos ... 0711924953
A0134 or A0154: Mono, Red. Has a Moseley Vibrato. May be A0134, but I can't tell the last digit very well.
https://www.sheltonsguitars.com/2008/1- ... 08-08.html
A0291: Stereo, Brown Burst. It seems most likely to be A0291, judging from other Brown Burst guitars near this number and by how the 9 stamp appears on other guitars. This guitar has a Nut instead of its original String Guide. This is the guitar photographed on the side of this page, under the description for the 350 model:
https://reverb.com/p/mosrite-stereo-350-sunburst-1972
A0304: Stereo, "Bright" Sunburst (compared to the brown ones.) Appears to be A0304, but it's hard to tell. Knobs aren't the "M" type (but are possibly original.) Was apparently for sale from Detroit Guitar, since it's posted to their Pinterest page. https://www.pinterest.com/pin/552605816757739103/

Unknown #s - 13:

A0xxx: Stereo. Black. Owned by Lil' Jimmy Reed, and is customized; has "Lil' Reed" on the body and headstock. It may be somewhere over A0300, judging by the numbers of known Black 350s. Video from 2013: https://youtu.be/ZYc0CtwvItQ
A0xxx: Stereo, Brown. Was for sale on eBay on March 24, 2011. Photos have been saved.

A0xxx: Stereo, Natural. Doesn't have M Knobs. Pic saved. Body was heavily cut away to look more teardrop-ish. Found on Facebook, posted by Larry's Guitars. I think I can still see at least one number on it, but I can't quite tell what it is.
A0xxx: Stereo, Natural. Appears to be in the first 100, but I can't tell for sure if it's A0057, A0067, A0069 or A0075. Appeared in late 2020, from Jean-sebastien's saucisserie shop in Baie Des Sables, Canada.: https://reverb.com/item/37253942-mosrit ... -week-deal

A0xxx: Stereo, Natural (or slightly more brown.) May have lost its # in a Refret (judging from photos) though I'm not certain if it did lose the #. Formerly owned by Will Speer (Will S on the forum) and was played in a 2007/2008 video from Rockongoodpeople. viewtopic.php?f=6&t=1942&p=19381#p19381

--------------

94 instruments are listed (or fewer, due to the unknown and speculation sections.) 1 350 Stereo Bass, AB0019, added in this update.

4 300 Basses,
4 300 Guitars,

1 Speculated # 300 Guitar
1 Partial # 300 Bass,

1 No Number 350 Bass,
9 350 Basses,
2 Speculated # 350 Basses,

47 350 Guitars - 11 or 12 Mono, 35 or 36 Stereo.

1 350 Guitar with a partial #,
5 350 Guitars with speculated #s,
1 Guitar that's a Partsrite,

6 Unknown 350 Basses
13 Unknown 350 Guitars.

Finishes Accounted For:

Black - Shows up late in the model run. (Earliest known guitar is A0237, though I wonder if it's really 337, and the earliest bass is AB117 - which happens to currently be the highest # for a Stereo 350 Bass.)
Blue - 3 accounted for.
Brown.
Brown Burst.
Natural - This is the most common finish seen. About the first 60 seem to be Natural, though without each one individually accounted for, I can't say that for certain.
Red.
Red, Translucent. (A0065.)
Red Burst.
Sunburst - 1 accounted for, though it may not be an original finish. The guitar is a speculated (but highly likely to be) A0304.
Yellow - 2 accounted for. (1 mystery bass, and Guitar A0345.) Perhaps these are the only 2, and they were ordered at the same time.
White - 1 mystery # bass accounted for.

Also, Guitar A0350 was once described as "Forest Green," in the ad where forum member "GTSP" bought it. I'm not sure if it's really a Dark Green, or a Black finish.

I feel confident that the Black, Brown, Brown Burst, Red, and Red Burst instruments are all original finishes. The Yellow ones might also be original, since I've found two of them that look nearly the same.

I'm not so sure about the originality of the Blue ones, the Green/Black one, or the White one. If I had better pics of the Unknown # Blue one, I could more easily tell.

Re: Mosrite 300 and 350 Serial Numbers? (Guitar and Bass)

Postby 101Volts » Sun May 23, 2021 12:12 pm

Second update for May 23, 2021:

A few errors in sentences fixed.

Update for May 23, 2021:

More info to the Red Partsrite "Super 350" Guitar added.

Also changed the speculated Red Guitar with a Mosley Tailpiece to "A0134 or A0154," instead of "A013x or A015x." I can't tell the last digit very well, but it seems to be a 4, and it's in the speculated # section anyway.

Update for May 21, 2021:

Unknown Brown Bass (possibly AB0047) added.

Also, I've added a speculated # section to the 350 Bass section, and I removed the probable AB0032 from the Partial # section to the Speculated section.

Legend:

An instrument new to the list (or moved from an Unknown section) as of the day the list is updated, whether the instrument has a number or not, will have Bold and Underscored Text for its Serial Number (or "unknown number") to stand out. (Examples: A0100 and A0xxx [Unknown 350 Guitar Example.]) When one of these marks is new, I'll also keep it in bold underscored text in the following update, but I'll remove the marks in the update after that.

Instruments that are finished in any kind except Natural, White or Yellow will have their finish set in colored text, except for Black. Black instruments will use Bold Text, to stand out more clearly.

Model Trivia:

300 models are 1-Pickup (in stock form) models. They came as Guitar and Bass. Few have shown up, though I don't think they'd be any more valuable than a 350 model in 2021.

350 models are 2-pickup models which came as Guitar and Bass. There are "Stereo" (2 cord output) and "Mono" (1 cord output) models of each Guitar and Bass, and it appears that Stereo models are more common than Mono models.

K0005: Natural. Has 1 Stock Neck Pup. Pic saved. Also has initials, "E.W.," beneath the serial number. Owned by Alan Manoian, who also owns 350 Guitar A0150. http://www.mosriteforum.com/forum/viewtopic.php?t=357
K0006: Natural. Owned by forum member mosriteforever. Mentioned at the same link as K0005, above.
K0010: ? One probably stock humbucking pup at neck position, no bridge pup. Mentioned first here, by Moaimen: viewtopic.php?p=71576#p71576
K0016: ? Has a probably stock and slanted Neck Humbucker, and a Single Coil Bridge Pup (which was probably added later.) It has 2 knobs, 3 switches, and Mono wiring. Mentioned first here, by Moaimen: viewtopic.php?p=71576#p71576

Speculated # Section - 1 Guitar:

K0009: Natural. Pic saved. Vaguely appears to be K0009, but I can't tell for sure in the photo. Doesn't have its stock pickup installed at the moment. It has been drilled to have a Bridge Pickup, too. It has a Bill Lawrence pup in the Bridge, a Seymour Duncan P90 in the neck, and an extra knob. Owned by forum member "rtdreep," who has owned it since 1978 (roughly speaking.) He does have the stock pickup, though. The guitar was mentioned in the forum, here: viewtopic.php?f=4&t=7994

AB0036: Stereo, Blue. Photos and page saved. Has a Maple neck. Ad says the body's made of Alder. This finish may be original, since it looks old, and it looks like it aged like other 350s. This is the second Blue 350 I've seen; A0148 (a Guitar) is also Blue. https://reverb.com/item/34060236-mosrit ... blue-1970s Photos from 2016, before this instrument was for sale on Reverb, show this instrument without a Mosrite logo.

A0271, Stereo, Brown Burst. Pics and page archived. Sold by "hammondguy" on eBay on October 29, 2020 for $1,195. Has been refretted, and the zero fret is now stainless.
A0293, Stereo, Red Burst. Pics saved. A clear photo of it was posted on Facebook from "Blues Rock" in Hong Kong, and I saved the photo. This is highly likely to be the guitar I linked in the Reverb ad; the wood matches up. If it is the same guitar, they bought it without M Knobs, and added M Knobs later (which may or may not be accurate to how it was originally sold.) The older Reverb photos are barely legible, but I made out that they seemed to be A025? or A029?, judging by the closer photo. Reverb ad:
https://reverb.com/price-guide/guide/24 ... 0-1974-red
A0309, Stereo, "Walnut Burst" (probably a Brown Burst.) Had a nut instead of a metal string guide when it showed up in February 2014. I posted it years ago: viewtopic.php?f=27&t=6118
A0329, Stereo, Black. Has M Knobs, and has a Bigsby added. Once owned by Michael Marks. http://home.insightbb.com/~marksma/wsb/ ... 63768.html
A0331, Stereo, Black, Owned by Forum Member In-stereo.
A0344, Stereo, Black. Nate Gibson's Guitar. Pics saved. Has been customized and repaired, and it has M Knobs. The pinstriping on it was done by Charlie Decker, the Armrest and Pickguard by Sarah here on the forum, and Evan Williamson worked on the crumbling binding. Also, I saved a photo of what's probably it, pre-customization, from Eastwood Guitars' site. I tried, and I was then able to make out the numbers as being "A0?44:" https://eastwoodcustoms.com/projects/mosrite-350/
A0345, Stereo, Yellow. Pics and page saved. Knobs are teardrop shaped. Listed on Reverb by Poway Jewelry and Loanon September 20, 2019. https://reverb.com/item/28163955-vintag ... ric-guitar

A0350: Stereo. Black or Forest Green. Pics saved. A seller called this finish "Forest Green." Owned by forum member GTSP (as noted in the second link below.) Photos saved from his Photobucket page. It looks Black instead of Green to me, but maybe it's just the lighting in Jayson's photos, since I vaguely remember this guitar being green. Serial # is according to Jayson.

Speculated # Section - 5 Guitars

Numbers in this section are as close as I could speculate, after looking at photos or by other speculation.

A0006? Stereo. "Light colored body wood." Seller gave number as "9000 V," which I suppose could have been read upside down. This is not confirmed, though. First mentioned here, by moaimen: viewtopic.php?p=71576#p71576
A0038: Stereo, Natural, stock. Belongs to Tim Brennan. Can be seen at his Facebook post, here: https://www.facebook.com/Tymguitars/pos ... 0711924953
A0134 or A0154: Mono, Red. Has a Moseley Vibrato. May be A0134, but I can't tell the last digit very well.
https://www.sheltonsguitars.com/2008/1- ... 08-08.html
A0291: Stereo, Brown Burst. It seems most likely to be A0291, judging from other Brown Burst guitars near this number and by how the 9 stamp appears on other guitars. This guitar has a Nut instead of its original String Guide. This is the guitar photographed on the side of this page, under the description for the 350 model:
https://reverb.com/p/mosrite-stereo-350-sunburst-1972
A0304: Stereo, "Bright" Sunburst (compared to the brown ones.) Appears to be A0304, but it's hard to tell. Knobs aren't the "M" type (but are possibly original.) Was apparently for sale from Detroit Guitar, since it's posted to their Pinterest page. https://www.pinterest.com/pin/552605816757739103/

Unknown #s - 13:

A0xxx: Stereo. Black. Owned by Lil' Jimmy Reed, and is customized; has "Lil' Reed" on the body and headstock. It may be somewhere over A0300, judging by the numbers of known Black 350s. Video from 2013: https://youtu.be/ZYc0CtwvItQ
A0xxx: Stereo, Brown. Was for sale on eBay on March 24, 2011. Photos have been saved.

A0xxx: Stereo, Natural. Doesn't have M Knobs. Pic saved. Body was heavily cut away to look more teardrop-ish. Found on Facebook, posted by Larry's Guitars. I think I can still see at least one number on it, but I can't quite tell what it is.
A0xxx: Stereo, Natural. Appears to be in the first 100, but I can't tell for sure if it's A0057, A0067, A0069 or A0075. Appeared in late 2020, from Jean-sebastien's saucisserie shop in Baie Des Sables, Canada.: https://reverb.com/item/37253942-mosrit ... -week-deal

A0xxx: Stereo, Natural (or slightly more brown.) May have lost its # in a Refret (judging from photos) though I'm not certain if it did lose the #. Formerly owned by Will Speer (Will S on the forum) and was played in a 2007/2008 video from Rockongoodpeople. viewtopic.php?f=6&t=1942&p=19381#p19381

--------------

94 instruments are listed (or fewer, due to the unknown and speculation sections.)

4 300 Basses,
4 300 Guitars,

1 Speculated # 300 Guitar
1 Partial # 300 Bass,

1 No Number 350 Bass,
9 350 Basses,
2 Speculated # 350 Basses,

47 350 Guitars - 11 or 12 Mono, 35 or 36 Stereo.

1 350 Guitar with a partial #,
5 350 Guitars with speculated #s,
1 Guitar that's a Partsrite,

6 Unknown 350 Basses
13 Unknown 350 Guitars.

Finishes Accounted For:

Black - Shows up late in the model run. (Earliest known guitar is A0237, though I wonder if it's really 337, and the earliest bass is AB117 - which happens to currently be the highest # for a Stereo 350 Bass.)
Blue - 3 accounted for.
Brown.
Brown Burst.
Natural - This is the most common finish seen. About the first 60 seem to be Natural, though without each one individually accounted for, I can't say that for certain.
Red.
Red, Translucent. (A0065.)
Red Burst.
Sunburst - 1 accounted for, though it may not be an original finish. The guitar is a speculated (but highly likely to be) A0304.
Yellow - 2 accounted for. (1 mystery bass, and Guitar A0345.) Perhaps these are the only 2, and they were ordered at the same time.
White - 1 mystery # bass accounted for.

Also, Guitar A0350 was once described as "Forest Green," in the ad where forum member "GTSP" bought it. I'm not sure if it's really a Dark Green, or a Black finish.

I feel confident that the Black, Brown, Brown Burst, Red, and Red Burst instruments are all original finishes. The Yellow ones might also be original, since I've found two of them that look nearly the same.

I'm not so sure about the originality of the Blue ones, the Green/Black one, or the White one. If I had better pics of the Unknown # Blue one, I could more easily tell.

Re: Mosrite 300 and 350 Serial Numbers? (Guitar and Bass)

Postby 101Volts » Mon May 24, 2021 1:54 pm

Update for May 24, 2021:

300 Bass KB0032 (Brown, 1 Bridge Pup) added. Showed up on eBay.

https://www.ebay.com/itm/265171948987?h ... 000%7C7000

Second update for May 23, 2021:

A few errors in sentences fixed.

Update for May 23, 2021:

More info to the Red Partsrite "Super 350" Guitar added.

Also changed the speculated Red Guitar with a Mosley Tailpiece to "A0134 or A0154," instead of "A013x or A015x." I can't tell the last digit very well, but it seems to be a 4, and it's in the speculated # section anyway.

Legend:

An instrument new to the list (or moved from an Unknown section) as of the day the list is updated, whether the instrument has a number or not, will have Bold and Underscored Text for its Serial Number (or "unknown number") to stand out. (Examples: A0100 and A0xxx [Unknown 350 Guitar Example.]) When one of these marks is new, I'll also keep it in bold underscored text in the following update, but I'll remove the marks in the update after that.

Instruments that are finished in any kind except Natural, White or Yellow will have their finish set in colored text, except for Black. Black instruments will use Bold Text, to stand out more clearly.

Model Trivia:

300 models are 1-Pickup (in stock form) models. They came as Guitar and Bass. Few have shown up, though I don't think they'd be any more valuable than a 350 model in 2021. Basses had the pickup both in the Neck position, and Bridge position. Guitars seem to have only had the pickup in the Neck position, but the list is incomplete, yet.

350 models are 2-pickup models that came as Guitar and Bass. There are "Stereo" (2 cord output) and "Mono" (1 cord output) models of each Guitar and Bass, and it appears that Stereo models are more common than Mono models. The Mono models only seem to have been made between A0100 and A0185, and not all of those are Mono models.

K0006: Natural. Owned by forum member mosriteforever. Mentioned at the same link as K0005, above.
K0010: ? One probably stock humbucking pup at neck position, no bridge pup. Mentioned first here, by Moaimen: viewtopic.php?p=71576#p71576
K0016: ? Has a probably stock and slanted Neck Humbucker, and a Single Coil Bridge Pup (which was probably added later.) It has 2 knobs, 3 switches, and Mono wiring. Mentioned first here, by Moaimen: viewtopic.php?p=71576#p71576

Speculated # Section - 1 Guitar:

K0009: Natural. Pic saved. Vaguely appears to be K0009, but I can't tell for sure in the photo. Doesn't have its stock pickup installed at the moment. It has been drilled to have a Bridge Pickup, too. It has a Bill Lawrence pup in the Bridge, a Seymour Duncan P90 in the neck, and an extra knob. Owned by forum member "rtdreep," who has owned it since 1978 (roughly speaking.) He does have the stock pickup, though. The guitar was mentioned in the forum, here: viewtopic.php?f=4&t=7994

AB0036: Stereo, Blue. Photos and page saved. Has a Maple neck. Ad says the body's made of Alder. This finish may be original, since it looks old, and it looks like it aged like other 350s. This is the second Blue 350 I've seen; A0148 (a Guitar) is also Blue. https://reverb.com/item/34060236-mosrit ... blue-1970s Photos from 2016, before this instrument was for sale on Reverb, show this instrument without a Mosrite logo.

Speculated #s - 2:

AB0032: Stereo, Red. - Was on eBay Australia in March 2010, for sale by seller "waitebt." This is likely to be AB0032, but I can't make out the A, or the first digit after the B.
AB0047: Stereo, Brown. I'm not sure of the 4 that I read, but I'm more confident that there's a 7 at the end. - 2 Piece Neck. Pic and page saved. http://www.oldfrets.com/Mosrite.html

AB0xxx: Stereo, Lemon Yellow/Aged White Finish. Was on eBay in February 2011. Pics saved. Doesn't have Mosrite M Knobs (just like A0345 which is also Yellow,) and it appears that Mosrite used cheaper knobs late in the model run.

A0271, Stereo, Brown Burst. Pics and page archived. Sold by "hammondguy" on eBay on October 29, 2020 for $1,195. Has been refretted, and the zero fret is now stainless.
A0293, Stereo, Red Burst. Pics saved. A clear photo of it was posted on Facebook from "Blues Rock" in Hong Kong, and I saved the photo. This is highly likely to be the guitar I linked in the Reverb ad; the wood matches up. If it is the same guitar, they bought it without M Knobs, and added M Knobs later (which may or may not be accurate to how it was originally sold.) The older Reverb photos are barely legible, but I made out that they seemed to be A025? or A029?, judging by the closer photo. Reverb ad:
https://reverb.com/price-guide/guide/24 ... 0-1974-red
A0309, Stereo, "Walnut Burst" (probably a Brown Burst.) Had a nut instead of a metal string guide when it showed up in February 2014. I posted it years ago: viewtopic.php?f=27&t=6118
A0329, Stereo, Black. Has M Knobs, and has a Bigsby added. Once owned by Michael Marks. http://home.insightbb.com/~marksma/wsb/ ... 63768.html
A0331, Stereo, Black, Owned by Forum Member In-stereo.
A0344, Stereo, Black. Nate Gibson's Guitar. Pics saved. Has been customized and repaired, and it has M Knobs. The pinstriping on it was done by Charlie Decker, the Armrest and Pickguard by Sarah here on the forum, and Evan Williamson worked on the crumbling binding. Also, I saved a photo of what's probably it, pre-customization, from Eastwood Guitars' site. I tried, and I was then able to make out the numbers as being "A0?44:" https://eastwoodcustoms.com/projects/mosrite-350/
A0345, Stereo, Yellow. Pics and page saved. Knobs are teardrop shaped. Listed on Reverb by Poway Jewelry and Loanon September 20, 2019. https://reverb.com/item/28163955-vintag ... ric-guitar
A0349: Stereo. Natural. Knobs are Plastic, probably original. Sold by "Big Brothers Pawn Springdale" in
Springdale, AR, United States. Price: $1,100 + $150 shipping. https://reverb.com/item/39740038-mosrit ... s-mahogany
A0350: Stereo. Black or Forest Green. Pics saved. A seller called this finish "Forest Green." Owned by forum member GTSP (as noted in the second link below.) Photos saved from his Photobucket page. It looks Black instead of Green to me, but maybe it's just the lighting in Jayson's photos, since I vaguely remember this guitar being green. Serial # is according to Jayson. Thanks for sharing the number.

Speculated # Section - 5 Guitars

Numbers in this section are as close as I could speculate, after looking at photos or by other speculation.

A0006? Stereo. "Light colored body wood." Seller gave number as "9000 V," which I suppose could have been read upside down. This is not confirmed, though. First mentioned here, by moaimen: viewtopic.php?p=71576#p71576
A0038: Stereo, Natural, stock. Belongs to Tim Brennan. Can be seen at his Facebook post, here: https://www.facebook.com/Tymguitars/pos ... 0711924953
A0134 or A0154: Mono, Red. Has a Moseley Vibrato. May be A0134, but I can't tell the last digit very well.
https://www.sheltonsguitars.com/2008/1- ... 08-08.html
A0291: Stereo, Brown Burst. It seems most likely to be A0291, judging from other Brown Burst guitars near this number and by how the 9 stamp appears on other guitars. This guitar has a Nut instead of its original String Guide. This is the guitar photographed on the side of this page, under the description for the 350 model:
https://reverb.com/p/mosrite-stereo-350-sunburst-1972
A0304: Stereo, "Bright" Sunburst (compared to the brown ones.) Appears to be A0304, but it's hard to tell. Knobs aren't the "M" type (but are possibly original.) Was apparently for sale from Detroit Guitar, since it's posted to their Pinterest page. https://www.pinterest.com/pin/552605816757739103/

Unknown #s - 13:

A0xxx: Stereo. Black. Owned by Lil' Jimmy Reed, and is customized; has "Lil' Reed" on the body and headstock. It may be somewhere over A0300, judging by the numbers of known Black 350s. Video from 2013: https://youtu.be/ZYc0CtwvItQ
A0xxx: Stereo, Brown. Was for sale on eBay on March 24, 2011. Photos have been saved.
A0xxx: Stereo, Dark Blue. Has M Knobs. Pic saved. Pic shared by Charley Johnson on Facebook. This is the third Blue 350 I've seen. I'm not sure if it's original, or refinished.
A0xxx: Stereo, Natural. Doesn't have M Knobs. Pic saved. Body was heavily cut away to look more teardrop-ish. Found on Facebook, posted by Larry's Guitars. I think I can still see at least one number on it, but I can't quite tell what it is.
A0xxx: Stereo, Natural. Appears to be in the first 100, but I can't tell for sure if it's A0057, A0067, A0069 or A0075. Appeared in late 2020, from Jean-sebastien's saucisserie shop in Baie Des Sables, Canada.: https://reverb.com/item/37253942-mosrit ... -week-deal
A0xxx: Stereo, Brown Burst.. Pic saved. I found the photo on Pinterest, and followed the link; it was down. I found the original ad in the Wayback Machine, but most of the photos weren't saved.

Tym Brennan's Unknown # 350s;
A0xxx: Mono, Natural. Has a Mosrite Single Coil in the bridge.
A0xxx: Mono, Dark Sunburst. Has a Maple Ventures neck, a Mosrite single coil in the neck position, and a Mosrite stop-tailpiece screwed into a Moseley Vibrato Base Plate. I question why the baseplate's installed.

All of Tym's 350s can be seen here:

May not have a # anymore:

A0xxx: Stereo, Natural. Pics saved. Doesn't have M Knobs. Has a Bigsby and a Tune O Matic, and was refretted twice (so it may no longer have a number.) Found on Facebook, posted by William R. Crabtree.
A0xxx: Stereo, Natural (or slightly more brown.) May have lost its # in a Refret (judging from photos) though I'm not certain if it did lose the #. Formerly owned by Will Speer (Will S on the forum) and was played in a 2007/2008 video from Rockongoodpeople. viewtopic.php?f=6&t=1942&p=19381#p19381

--------------

95 instruments are listed (or fewer, due to the unknown and speculation sections.)
1 300 Bass, KB0032, added in this update.

5 300 Basses,
4 300 Guitars,

1 Speculated # 300 Guitar
1 Partial # 300 Bass,

1 No Number 350 Bass,
9 350 Basses,
2 Speculated # 350 Basses,

47 350 Guitars - 11 or 12 Mono, 35 or 36 Stereo.

1 350 Guitar with a partial #,
5 350 Guitars with speculated #s,
1 Guitar that's a Partsrite,

6 Unknown 350 Basses
13 Unknown 350 Guitars.

Finishes Accounted For:

Black - Shows up late in the model run. (Earliest known guitar is A0237, though I wonder if it's really 337, and the earliest bass is AB117 - which happens to currently be the highest # for a Stereo 350 Bass.)
Blue - 3 accounted for.
Brown.
Brown Burst.
Natural - This is the most common finish seen. About the first 60 seem to be Natural, though without each one individually accounted for, I can't say that for certain.
Red.
Red, Translucent. (A0065.)
Red Burst.
Sunburst - 1 accounted for, though it may not be an original finish. The guitar is a speculated (but highly likely to be) A0304.
Yellow - 2 accounted for. (1 mystery bass, and Guitar A0345.) Perhaps these are the only 2, and they were ordered at the same time.
White - 1 mystery # bass accounted for.

Also, Guitar A0350 was once described as "Forest Green," in the ad where forum member "GTSP" bought it. I'm not sure if it's really a Dark Green, or a Black finish.

I feel confident that the Black, Brown, Brown Burst, Red, and Red Burst instruments are all original finishes. The Yellow ones might also be original, since I've found two of them that look nearly the same.

I'm not so sure about the originality of the Blue ones, the Green/Black one, or the White one. If I had better pics of the Unknown # Blue one, I could more easily tell.

Re: Mosrite 300 and 350 Serial Numbers? (Guitar and Bass)

Postby 101Volts » Mon May 24, 2021 3:43 pm

Second Update for May 24, 2021:

KB0032 also has a Reverb ad, which I've added.

Update for May 24, 2021:

300 Bass KB0032 (Brown, 1 Bridge Pup) added. Showed up on eBay.

https://www.ebay.com/itm/265171948987?h ... 000%7C7000

Second update for May 23, 2021:

A few errors in sentences fixed.

Update for May 23, 2021:

More info to the Red Partsrite "Super 350" Guitar added.

Also changed the speculated Red Guitar with a Mosley Tailpiece to "A0134 or A0154," instead of "A013x or A015x." I can't tell the last digit very well, but it seems to be a 4, and it's in the speculated # section anyway.

Legend:

An instrument new to the list (or moved from an Unknown section) as of the day the list is updated, whether the instrument has a number or not, will have Bold and Underscored Text for its Serial Number (or "unknown number") to stand out. (Examples: A0100 and A0xxx [Unknown 350 Guitar Example.]) When one of these marks is new, I'll also keep it in bold underscored text in the following update, but I'll remove the marks in the update after that.

Instruments that are finished in any kind except Natural, White or Yellow will have their finish set in colored text, except for Black. Black instruments will use Bold Text, to stand out more clearly.

Model Trivia:

300 models are 1-Pickup (in stock form) models. They came as Guitar and Bass. Few have shown up, though I don't think they'd be any more valuable than a 350 model in 2021. Basses had the pickup both in the Neck position, and Bridge position. Guitars seem to have only had the pickup in the Neck position, but the list is incomplete, yet.

350 models are 2-pickup models that came as Guitar and Bass. There are "Stereo" (2 cord output) and "Mono" (1 cord output) models of each Guitar and Bass, and it appears that Stereo models are more common than Mono models. The Mono models only seem to have been made between A0100 and A0185, and not all of those are Mono models.

300 Models:

K0016: ? Has a probably stock and slanted Neck Humbucker, and a Single Coil Bridge Pup (which was probably added later.) It has 2 knobs, 3 switches, and Mono wiring. Mentioned first here, by Moaimen: viewtopic.php?p=71576#p71576

Speculated # Section - 1 Guitar:

K0009: Natural. Pic saved. Vaguely appears to be K0009, but I can't tell for sure in the photo. Doesn't have its stock pickup installed at the moment. It has been drilled to have a Bridge Pickup, too. It has a Bill Lawrence pup in the Bridge, a Seymour Duncan P90 in the neck, and an extra knob. Owned by forum member "rtdreep," who has owned it since 1978 (roughly speaking.) He does have the stock pickup, though. The guitar was mentioned in the forum, here: viewtopic.php?f=4&t=7994

AB0036: Stereo, Blue. Photos and page saved. Has a Maple neck. Ad says the body's made of Alder. This finish may be original, since it looks old, and it looks like it aged like other 350s. This is the second Blue 350 I've seen; A0148 (a Guitar) is also Blue. https://reverb.com/item/34060236-mosrit ... blue-1970s Photos from 2016, before this instrument was for sale on Reverb, show this instrument without a Mosrite logo.

Speculated #s - 2:

AB0032: Stereo, Red. - Was on eBay Australia in March 2010, for sale by seller "waitebt." This is likely to be AB0032, but I can't make out the A, or the first digit after the B.

AB0xxx: Stereo, Lemon Yellow/Aged White Finish. Was on eBay in February 2011. Pics saved. Doesn't have Mosrite M Knobs (just like A0345 which is also Yellow,) and it appears that Mosrite used cheaper knobs late in the model run.

A0271, Stereo, Brown Burst. Pics and page archived. Sold by "hammondguy" on eBay on October 29, 2020 for $1,195. Has been refretted, and the zero fret is now stainless.
A0293, Stereo, Red Burst. Pics saved. A clear photo of it was posted on Facebook from "Blues Rock" in Hong Kong, and I saved the photo. This is highly likely to be the guitar I linked in the Reverb ad; the wood matches up. If it is the same guitar, they bought it without M Knobs, and added M Knobs later (which may or may not be accurate to how it was originally sold.) The older Reverb photos are barely legible, but I made out that they seemed to be A025? or A029?, judging by the closer photo. Reverb ad:
https://reverb.com/price-guide/guide/24 ... 0-1974-red
A0309, Stereo, "Walnut Burst" (probably a Brown Burst.) Had a nut instead of a metal string guide when it showed up in February 2014. I posted it years ago: viewtopic.php?f=27&t=6118
A0329, Stereo, Black. Has M Knobs, and has a Bigsby added. Once owned by Michael Marks. http://home.insightbb.com/~marksma/wsb/ ... 63768.html
A0331, Stereo, Black, Owned by Forum Member In-stereo.
A0344, Stereo, Black. Nate Gibson's Guitar. Pics saved. Has been customized and repaired, and it has M Knobs. The pinstriping on it was done by Charlie Decker, the Armrest and Pickguard by Sarah here on the forum, and Evan Williamson worked on the crumbling binding. Also, I saved a photo of what's probably it, pre-customization, from Eastwood Guitars' site. I tried, and I was then able to make out the numbers as being "A0?44:" https://eastwoodcustoms.com/projects/mosrite-350/
A0345, Stereo, Yellow. Pics and page saved. Knobs are teardrop shaped. Listed on Reverb by Poway Jewelry and Loanon September 20, 2019. https://reverb.com/item/28163955-vintag ... ric-guitar
A0349: Stereo. Natural. Knobs are Plastic, probably original. Sold by "Big Brothers Pawn Springdale" in
Springdale, AR, United States. Price: $1,100 + $150 shipping. https://reverb.com/item/39740038-mosrit ... s-mahogany
A0350: Stereo. Black or Forest Green. Pics saved. A seller called this finish "Forest Green." Owned by forum member GTSP (as noted in the second link below.) Photos saved from his Photobucket page. It looks Black instead of Green to me, but maybe it's just the lighting in Jayson's photos, since I vaguely remember this guitar being green. Serial # is according to Jayson. Thanks for sharing the number.

Speculated # Section - 5 Guitars

Numbers in this section are as close as I could speculate, after looking at photos or by other speculation.

A0006? Stereo. "Light colored body wood." Seller gave number as "9000 V," which I suppose could have been read upside down. This is not confirmed, though. First mentioned here, by moaimen: viewtopic.php?p=71576#p71576
A0038: Stereo, Natural, stock. Belongs to Tim Brennan. Can be seen at his Facebook post, here: https://www.facebook.com/Tymguitars/pos ... 0711924953
A0134 or A0154: Mono, Red. Has a Moseley Vibrato. May be A0134, but I can't tell the last digit very well.
https://www.sheltonsguitars.com/2008/1- ... 08-08.html
A0291: Stereo, Brown Burst. It seems most likely to be A0291, judging from other Brown Burst guitars near this number and by how the 9 stamp appears on other guitars. This guitar has a Nut instead of its original String Guide. This is the guitar photographed on the side of this page, under the description for the 350 model:
https://reverb.com/p/mosrite-stereo-350-sunburst-1972
A0304: Stereo, "Bright" Sunburst (compared to the brown ones.) Appears to be A0304, but it's hard to tell. Knobs aren't the "M" type (but are possibly original.) Was apparently for sale from Detroit Guitar, since it's posted to their Pinterest page. https://www.pinterest.com/pin/552605816757739103/

Unknown #s - 13:

A0xxx: Stereo. Black. Owned by Lil' Jimmy Reed, and is customized; has "Lil' Reed" on the body and headstock. It may be somewhere over A0300, judging by the numbers of known Black 350s. Video from 2013: https://youtu.be/ZYc0CtwvItQ
A0xxx: Stereo, Brown. Was for sale on eBay on March 24, 2011. Photos have been saved.

A0xxx: Stereo, Natural. Doesn't have M Knobs. Pic saved. Body was heavily cut away to look more teardrop-ish. Found on Facebook, posted by Larry's Guitars. I think I can still see at least one number on it, but I can't quite tell what it is.
A0xxx: Stereo, Natural. Appears to be in the first 100, but I can't tell for sure if it's A0057, A0067, A0069 or A0075. Appeared in late 2020, from Jean-sebastien's saucisserie shop in Baie Des Sables, Canada.: https://reverb.com/item/37253942-mosrit ... -week-deal

A0xxx: Stereo, Natural (or slightly more brown.) May have lost its # in a Refret (judging from photos) though I'm not certain if it did lose the #. Formerly owned by Will Speer (Will S on the forum) and was played in a 2007/2008 video from Rockongoodpeople. viewtopic.php?f=6&t=1942&p=19381#p19381

--------------

95 instruments are listed (or fewer, due to the unknown and speculation sections.)
1 300 Bass, KB0032, added in this update.

5 300 Basses,
4 300 Guitars,

1 Speculated # 300 Guitar
1 Partial # 300 Bass,

1 No Number 350 Bass,
9 350 Basses,
2 Speculated # 350 Basses,

47 350 Guitars - 11 or 12 Mono, 35 or 36 Stereo.

1 350 Guitar with a partial #,
5 350 Guitars with speculated #s,
1 Guitar that's a Partsrite,

6 Unknown 350 Basses
13 Unknown 350 Guitars.

Finishes Accounted For:

Black - Shows up late in the model run. (Earliest known guitar is A0237, though I wonder if it's really 337, and the earliest bass is AB117 - which happens to currently be the highest # for a Stereo 350 Bass.)
Blue - 3 accounted for.
Brown.
Brown Burst.
Natural - This is the most common finish seen. About the first 60 seem to be Natural, though without each one individually accounted for, I can't say that for certain.
Red.
Red, Translucent. (A0065.)
Red Burst.
Sunburst - 1 accounted for, though it may not be an original finish. The guitar is a speculated (but highly likely to be) A0304.
Yellow - 2 accounted for. (1 mystery bass, and Guitar A0345.) Perhaps these are the only 2, and they were ordered at the same time.
White - 1 mystery # bass accounted for.

Also, Guitar A0350 was once described as "Forest Green," in the ad where forum member "GTSP" bought it. I'm not sure if it's really a Dark Green, or a Black finish.

I feel confident that the Black, Brown, Brown Burst, Red, and Red Burst instruments are all original finishes. The Yellow ones might also be original, since I've found two of them that look nearly the same.

I'm not so sure about the originality of the Blue ones, the Green/Black one, or the White one. If I had better pics of the Unknown # Blue one, I could more easily tell.

Re: Mosrite 300 and 350 Serial Numbers? (Guitar and Bass)

Postby 101Volts » Sat Jun 05, 2021 1:35 pm

Update for June 5, 2021:

One unknown # 350 Guitar found. It's a late model, as it has the cheaper knobs.

Second Update for May 24, 2021:

KB0032 also has a Reverb ad, which I've added.

Update for May 24, 2021:

300 Bass KB0032 (Brown, 1 Bridge Pup) added. Showed up on eBay.

https://www.ebay.com/itm/265171948987?h ... 000%7C7000

Legend:

An instrument new to the list (or moved from an Unknown section) as of the day the list is updated, whether the instrument has a number or not, will have Bold and Underscored Text for its Serial Number (or "unknown number") to stand out. (Examples: A0100 and A0xxx [Unknown 350 Guitar Example.]) When one of these marks is new, I'll also keep it in bold underscored text in the following update, but I'll remove the marks in the update after that.

Instruments that are finished in any kind except Natural, White or Yellow will have their finish set in colored text, except for Black. Black instruments will use Bold Text, to stand out more clearly.

Model Trivia:

Both the 300 and 350 models are usually Mahogany-bodies and necked instruments, though we have 1 or 2 exceptions to the rule. They have typical Mosrite appointments; 24.5" scale length (Guitar,) 30" (or so, roughly speaking) Scale Length (Bass.) Mosrite Pickups. For these 300 and 350 models, these mostly have the rarer 1970s Mosrite Humbuckers that weren't (as far as I'm aware) available in other decades. (I could be wrong, I don't know the 1978 - 1992 models very well.)

300 models are 1-Pickup (in stock form) models. They came as Guitar and Bass. Few have shown up, though I don't think they'd be any more valuable than a 350 model in 2021. Basses had the pickup both in the Neck position, and Bridge position. Guitars seem to have only had the pickup in the Neck position, but the list is incomplete, yet.

350 models are 2-pickup models that came as Guitar and Bass. There are "Stereo" (2 cord output) and "Mono" (1 cord output) models of each Guitar and Bass, and it appears that Stereo models are more common than Mono models. The Mono models only seem to have been made between A0100 and A0185, and not all of those are Mono models.

Speculated # Section - 1 Guitar:

K0009: Natural. Pic saved. Vaguely appears to be K0009, but I can't tell for sure in the photo. Doesn't have its stock pickup installed at the moment. It has been drilled to have a Bridge Pickup, too. It has a Bill Lawrence pup in the Bridge, a Seymour Duncan P90 in the neck, and an extra knob. Owned by forum member "rtdreep," who has owned it since 1978 (roughly speaking.) He does have the stock pickup, though. The guitar was mentioned in the forum, here: viewtopic.php?f=4&t=7994

AB0036: Stereo, Blue. Photos and page saved. Has a Maple neck. Ad says the body's made of Alder. This finish may be original, since it looks old, and it looks like it aged like other 350s. This is the second Blue 350 I've seen; A0148 (a Guitar) is also Blue. https://reverb.com/item/34060236-mosrit ... blue-1970s Photos from 2016, before this instrument was for sale on Reverb, show this instrument without a Mosrite logo.

Speculated #s - 2:

AB0032: Stereo, Red. - Was on eBay Australia in March 2010, for sale by seller "waitebt." This is likely to be AB0032, but I can't make out the A, or the first digit after the B.

AB0xxx: Stereo, Lemon Yellow/Aged White Finish. Was on eBay in February 2011. Pics saved. Doesn't have Mosrite M Knobs (just like A0345 which is also Yellow,) and it appears that Mosrite used cheaper knobs late in the model run.

A0271, Stereo, Brown Burst. Pics and page archived. Sold by "hammondguy" on eBay on October 29, 2020 for $1,195. Has been refretted, and the zero fret is now stainless.
A0293, Stereo, Red Burst. Pics saved. A clear photo of it was posted on Facebook from "Blues Rock" in Hong Kong, and I saved the photo. This is highly likely to be the guitar I linked in the Reverb ad; the wood matches up. If it is the same guitar, they bought it without M Knobs, and added M Knobs later (which may or may not be accurate to how it was originally sold.) The older Reverb photos are barely legible, but I made out that they seemed to be A025? or A029?, judging by the closer photo. Reverb ad:
https://reverb.com/price-guide/guide/24 ... 0-1974-red
A0309, Stereo, "Walnut Burst" (probably a Brown Burst.) Had a nut instead of a metal string guide when it showed up in February 2014. I posted it years ago: viewtopic.php?f=27&t=6118
A0329, Stereo, Black. Has M Knobs, and has a Bigsby added. Once owned by Michael Marks. http://home.insightbb.com/~marksma/wsb/ ... 63768.html
A0331, Stereo, Black, Owned by Forum Member In-stereo.
A0344, Stereo, Black. Nate Gibson's Guitar. Pics saved. Has been customized and repaired, and it has M Knobs. The pinstriping on it was done by Charlie Decker, the Armrest and Pickguard by Sarah here on the forum, and Evan Williamson worked on the crumbling binding. Also, I saved a photo of what's probably it, pre-customization, from Eastwood Guitars' site. I tried, and I was then able to make out the numbers as being "A0?44:" https://eastwoodcustoms.com/projects/mosrite-350/
A0345, Stereo, Yellow. Pics and page saved. Knobs are teardrop shaped. Listed on Reverb by Poway Jewelry and Loanon September 20, 2019. https://reverb.com/item/28163955-vintag ... ric-guitar
A0349: Stereo. Natural. Knobs are Plastic, probably original. Sold by "Big Brothers Pawn Springdale" in
Springdale, AR, United States. Price: $1,100 + $150 shipping. https://reverb.com/item/39740038-mosrit ... s-mahogany
A0350: Stereo. Black or Forest Green. Pics saved. A seller called this finish "Forest Green." Owned by forum member GTSP (as noted in the second link below.) Photos saved from his Photobucket page. It looks Black instead of Green to me, but maybe it's just the lighting in Jayson's photos, since I vaguely remember this guitar being green. Serial # is according to Jayson. Thanks for sharing the number.

Speculated # Section - 5 Guitars

Numbers in this section are as close as I could speculate, after looking at photos or by other speculation.

A0006? Stereo. "Light colored body wood." Seller gave number as "9000 V," which I suppose could have been read upside down. This is not confirmed, though. First mentioned here, by moaimen: viewtopic.php?p=71576#p71576
A0038: Stereo, Natural, stock. Belongs to Tim Brennan. Can be seen at his Facebook post, here: https://www.facebook.com/Tymguitars/pos ... 0711924953
A0134 or A0154: Mono, Red. Has a Moseley Vibrato. May be A0134, but I can't tell the one digit very well.
https://www.sheltonsguitars.com/2008/1- ... 08-08.html
A0291: Stereo, Brown Burst. It seems most likely to be A0291, judging from other Brown Burst guitars near this number and by how the 9 stamp appears on other guitars. This guitar has a Nut instead of its original String Guide. This is the guitar photographed on the side of this page, under the description for the 350 model:
https://reverb.com/p/mosrite-stereo-350-sunburst-1972
A0304: Stereo, "Bright" Sunburst (compared to the brown ones.) Appears to be A0304, but it's hard to tell. Knobs aren't the "M" type (but are possibly original.) Was apparently for sale from Detroit Guitar, since it's posted to their Pinterest page. https://www.pinterest.com/pin/552605816757739103/

Unknown #s - 14:

A0xxx: Stereo. Black. Owned by Lil' Jimmy Reed, and is customized; has "Lil' Reed" on the body and headstock. It may be somewhere over A0300, judging by the numbers of known Black 350s. Video from 2013: https://youtu.be/ZYc0CtwvItQ
A0xxx: Stereo, Brown. Was for sale on eBay on March 24, 2011. Photos have been saved.

A0xxx: Stereo, Natural. Doesn't have M Knobs. Pic saved. Body was heavily cut away to look more teardrop-ish. Found on Facebook, posted by Larry's Guitars. I think I can still see at least one number on it, but I can't quite tell what it is.
A0xxx: Stereo, Natural. Appears to be in the first 100, but I can't tell for sure if it's A0057, A0067, A0069 or A0075. Appeared in late 2020, from Jean-sebastien's saucisserie shop in Baie Des Sables, Canada.: https://reverb.com/item/37253942-mosrit ... -week-deal
A0xxx: Stereo, Natural. It's a late model, since it has the cheaper knobs on it. Showed up in a video on Facebook, from Brian Edwards. https://www.facebook.com/brian.edwards. ... 6626059188
A0xxx: Stereo, Brown Burst.. Pic saved. I found the photo on Pinterest, and followed the link; it was down. I found the original ad in the Wayback Machine, but most of the photos weren't saved.

A0xxx: Mono, Dark Sunburst. Has a Maple Ventures neck, a Mosrite single coil in the neck position, and a Mosrite stop-tailpiece screwed into a Moseley Vibrato Base Plate. I question why the baseplate's installed.

All of Tym's 350s can be seen here:

May not have a # anymore:

A0xxx: Stereo, Natural. Pics saved. Doesn't have M Knobs. Has a Bigsby and a Tune O Matic, and was refretted twice (so it may no longer have a number.) Found on Facebook, posted by William R. Crabtree.
A0xxx: Stereo, Natural (or slightly more brown.) May have lost its # in a Refret (judging from photos) though I'm not certain if it did lose the #. Formerly owned by Will Speer (Will S on the forum) and was played in a 2007/2008 video from Rockongoodpeople. viewtopic.php?f=6&t=1942&p=19381#p19381

--------------

96 instruments are listed (or fewer, due to the unknown and speculation sections.)
1 300 Bass, KB0032, added in this update.

5 300 Basses,
4 300 Guitars,

1 Speculated # 300 Guitar
1 Partial # 300 Bass,

1 No Number 350 Bass,
9 350 Basses,
2 Speculated # 350 Basses,

48 350 Guitars - 11 or 12 Mono, 36 or 37 Stereo.

1 350 Guitar with a partial #,
5 350 Guitars with speculated #s,
1 Guitar that's a Partsrite,

6 Unknown 350 Basses
13 Unknown 350 Guitars.

Finishes Accounted For:

Black - Shows up late in the model run. (Earliest known guitar is A0237, though I wonder if it's really 337, and the earliest bass is AB117 - which happens to currently be the highest # for a Stereo 350 Bass.)
Blue - 3 accounted for.
Brown.
Brown Burst.
Natural - This is the most common finish seen. About the first 60 seem to be Natural, though without each one individually accounted for, I can't say that for certain.
Red.
Red, Translucent. (A0065.)
Red Burst.
Sunburst - 1 accounted for, though it may not be an original finish. The guitar is a speculated (but highly likely to be) A0304.
Yellow - 2 accounted for. (1 mystery bass, and Guitar A0345.) Perhaps these are the only 2, and they were ordered at the same time.
White - 1 mystery # bass accounted for.

Also, Guitar A0350 was once described as "Forest Green," in the ad where forum member "GTSP" bought it. I'm not sure if it's really a Dark Green, or a Black finish.

I feel confident that the Black, Brown, Brown Burst, Red, and Red Burst instruments are all original finishes. The Yellow ones might also be original, since I've found two of them that look nearly the same.

I'm not so sure about the originality of the Blue ones, the Green/Black one, or the White one. If I had better pics of the Unknown # Blue one, I could more easily tell.

Re: Mosrite 300 and 350 Serial Numbers? (Guitar and Bass)

Postby 101Volts » Tue Jun 29, 2021 8:39 pm

Update for June 29, 2021:

A0266, Stereo 350 in some Brown/Natural/Butterscotch-ish color added. https://reverb.com/item/41559486-mosrit ... 1973-brown

Update for June 5, 2021:

One unknown # 350 Guitar found. It's a late model, as it has the cheaper knobs.

Legend:

An instrument new to the list (or moved from an Unknown section) as of the day the list is updated, whether the instrument has a number or not, will have Bold and Underscored Text for its Serial Number (or "unknown number") to stand out. (Examples: A0100 and A0xxx [Unknown 350 Guitar Example.]) When one of these marks is new, I'll also keep it in bold underscored text in the following update, but I'll remove the marks in the update after that.

Instruments that are finished in any kind except Natural, White or Yellow will have their finish set in colored text, except for Black. Black instruments will use Bold Text, to stand out more clearly.

Model Trivia:

Both the 300 and 350 models are usually Mahogany-bodies and necked instruments, though we have 1 or 2 exceptions to the rule. They have typical Mosrite appointments; 24.5" scale length (Guitar,) 30" (or so, roughly speaking) Scale Length (Bass.) Mosrite Pickups. For these 300 and 350 models, these mostly have the rarer 1970s Mosrite Humbuckers that weren't (as far as I'm aware) available in other decades. (I could be wrong, I don't know the 1978 - 1992 models very well.)

300 models are 1-Pickup (in stock form) models. They came as Guitar and Bass. Few have shown up, though I don't think they'd be any more valuable than a 350 model in 2021. Basses had the pickup both in the Neck position, and Bridge position. Guitars seem to have only had the pickup in the Neck position, but the list is incomplete, yet.

350 models are 2-pickup models that came as Guitar and Bass. There are "Stereo" (2 cord output) and "Mono" (1 cord output) models of each Guitar and Bass, and it appears that Stereo models are more common than Mono models. The Mono models only seem to have been made between A0100 and A0185, and not all of those are Mono models.

Speculated # Section - 1 Guitar:

K0009: Natural. Pic saved. Vaguely appears to be K0009, but I can't tell for sure in the photo. Doesn't have its stock pickup installed at the moment. It has been drilled to have a Bridge Pickup, too. It has a Bill Lawrence pup in the Bridge, a Seymour Duncan P90 in the neck, and an extra knob. Owned by forum member "rtdreep," who has owned it since 1978 (roughly speaking.) He does have the stock pickup, though. The guitar was mentioned in the forum, here: viewtopic.php?f=4&t=7994

AB0036: Stereo, Blue. Photos and page saved. Has a Maple neck. Ad says the body's made of Alder. This finish may be original, since it looks old, and it looks like it aged like other 350s. This is the second Blue 350 I've seen; A0148 (a Guitar) is also Blue. https://reverb.com/item/34060236-mosrit ... blue-1970s Photos from 2016, before this instrument was for sale on Reverb, show this instrument without a Mosrite logo.

AB0xxx: Stereo, Lemon Yellow/Aged White Finish. Was on eBay in February 2011. Pics saved. Doesn't have Mosrite M Knobs (just like A0345 which is also Yellow,) and it appears that Mosrite used cheaper knobs late in the model run.

A0271, Stereo, Brown Burst. Pics and page archived. Sold by "hammondguy" on eBay on October 29, 2020 for $1,195. Has been refretted, and the zero fret is now stainless.
A0293, Stereo, Red Burst. Pics saved. A clear photo of it was posted on Facebook from "Blues Rock" in Hong Kong, and I saved the photo. This is highly likely to be the guitar I linked in the Reverb ad; the wood matches up. If it is the same guitar, they bought it without M Knobs, and added M Knobs later (which may or may not be accurate to how it was originally sold.) The older Reverb photos are barely legible, but I made out that they seemed to be A025? or A029?, judging by the closer photo. Reverb ad:
https://reverb.com/price-guide/guide/24 ... 0-1974-red
A0309, Stereo, "Walnut Burst" (probably a Brown Burst.) Had a nut instead of a metal string guide when it showed up in February 2014. I posted it years ago: viewtopic.php?f=27&t=6118

A0344, Stereo, Black. Nate Gibson's Guitar. Pics saved. Has been customized and repaired, and it has M Knobs. The pinstriping on it was done by Charlie Decker, the Armrest and Pickguard by Sarah here on the forum, and Evan Williamson worked on the crumbling binding. Also, I saved a photo of what's probably it, pre-customization, from Eastwood Guitars' site. I tried, and I was then able to make out the numbers as being "A0?44:" https://eastwoodcustoms.com/projects/mosrite-350/
A0345, Stereo, Yellow. Pics and page saved. Knobs are teardrop shaped. Listed on Reverb by Poway Jewelry and Loanon September 20, 2019. https://reverb.com/item/28163955-vintag ... ric-guitar

A0350: Stereo. Black or Forest Green. Pics saved. A seller called this finish "Forest Green." Owned by forum member GTSP (as noted in the second link below.) Photos saved from his Photobucket page. It looks Black instead of Green to me, but maybe it's just the lighting in Jayson's photos, since I vaguely remember this guitar being green. Serial # is according to Jayson.

Speculated # Section - 5 Guitars

Numbers in this section are as close as I could speculate, after looking at photos or by other speculation.

A0006? Stereo. "Light colored body wood." Seller gave number as "9000 V," which I suppose could have been read upside down. This is not confirmed, though. First mentioned here, by moaimen: viewtopic.php?p=71576#p71576
A0038: Stereo, Natural, stock. Belongs to Tim Brennan. Can be seen at his Facebook post, here: https://www.facebook.com/Tymguitars/pos ... 0711924953
A0134 or A0154: Mono, Red. Has a Moseley Vibrato. May be A0134, but I can't tell the one digit very well.
https://www.sheltonsguitars.com/2008/1- ... 08-08.html
A0291: Stereo, Brown Burst. It seems most likely to be A0291, judging from other Brown Burst guitars near this number and by how the 9 stamp appears on other guitars. This guitar has a Nut instead of its original String Guide. This is the guitar photographed on the side of this page, under the description for the 350 model:
https://reverb.com/p/mosrite-stereo-350-sunburst-1972
A0304: Stereo, "Bright" Sunburst (compared to the brown ones.) Appears to be A0304, but it's hard to tell. Knobs aren't the "M" type (but are possibly original.) Was apparently for sale from Detroit Guitar, since it's posted to their Pinterest page. https://www.pinterest.com/pin/552605816757739103/

Unknown #s - 14:

A0xxx: Stereo. Black. Owned by Lil' Jimmy Reed, and is customized; has "Lil' Reed" on the body and headstock. It may be somewhere over A0300, judging by the numbers of known Black 350s. Video from 2013: https://youtu.be/ZYc0CtwvItQ
A0xxx: Stereo, Brown. Was for sale on eBay on March 24, 2011. Photos have been saved.

A0xxx: Stereo, Natural. Doesn't have M Knobs. Pic saved. Body was heavily cut away to look more teardrop-ish. Found on Facebook, posted by Larry's Guitars. I think I can still see at least one number on it, but I can't quite tell what it is.
A0xxx: Stereo, Natural. Appears to be in the first 100, but I can't tell for sure if it's A0057, A0067, A0069 or A0075. Appeared in late 2020, from Jean-sebastien's saucisserie shop in Baie Des Sables, Canada.: https://reverb.com/item/37253942-mosrit ... -week-deal

A0xxx: Stereo, Natural. Pics saved. Doesn't have M Knobs. Has a Bigsby and a Tune O Matic, and was refretted twice (so it may no longer have a number.) Found on Facebook, posted by William R. Crabtree.
A0xxx: Stereo, Natural (or slightly more brown.) May have lost its # in a Refret (judging from photos) though I'm not certain if it did lose the #. Formerly owned by Will Speer (Will S on the forum) and was played in a 2007/2008 video from Rockongoodpeople. viewtopic.php?f=6&t=1942&p=19381#p19381

--------------

97 instruments are listed (or fewer, due to the unknown and speculation sections.)

5 300 Basses,
4 300 Guitars,

1 Speculated # 300 Guitar
1 Partial # 300 Bass,

1 No Number 350 Bass,
9 350 Basses,
2 Speculated # 350 Basses,

49 350 Guitars - 11 or 12 Mono, 37 or 38 Stereo.

1 350 Guitar with a partial #,
5 350 Guitars with speculated #s,
1 Guitar that's a Partsrite,

6 Unknown 350 Basses
13 Unknown 350 Guitars.

Finishes Accounted For:

Black - Shows up late in the model run. (Earliest known guitar is A0237, though I wonder if it's really 337, and the earliest bass is AB117 - which happens to currently be the highest # for a Stereo 350 Bass.)
Blue - 3 accounted for.
Brown.
Brown Burst.
Natural - This is the most common finish seen. About the first 60 seem to be Natural, though without each one individually accounted for, I can't say that for certain.
Red.
Red, Translucent. (A0065.)
Red Burst.
Sunburst - 1 accounted for, though it may not be an original finish. The guitar is a speculated (but highly likely to be) A0304.
Yellow - 2 accounted for. (1 mystery bass, and Guitar A0345.) Perhaps these are the only 2, and they were ordered at the same time.
White - 1 mystery # bass accounted for.

Also, Guitar A0350 was once described as "Forest Green," in the ad where forum member "GTSP" bought it. I'm not sure if it's really a Dark Green, or a Black finish.

A0266 seems to be a Translucent Brown or Translucent Butterscotch color, strangely enough.

I feel confident that the Black, Brown, Brown Burst, Red, and Red Burst instruments are all original finishes. The Yellow ones might also be original, since I've found two of them that look nearly the same.

I'm not so sure about the originality of the Blue ones, the Green/Black one, or the White one. If I had better pics of the Unknown # Blue one, I could more easily tell.

Re: Mosrite 300 and 350 Serial Numbers? (Guitar and Bass)

Postby 101Volts » Thu Oct 14, 2021 5:35 pm

Latest Updates:

Update for 14th of October, 2021:

One Guitar added to the speculated # section. Somehow, I missed adding it here before. This is a Stereo Brown Burst belonging to one Kenneth Ray West, and I can only tell a probable first digit, making it now known as a A03xx number.

Update for 29th of June, 2021:

A0266, Stereo 350 in some Brown/Natural/Butterscotch-ish color added. https://reverb.com/item/41559486-mosrit ... 1973-brown

Legend:

An instrument new to the list (or moved from an Unknown section) as of the day the list is updated, whether the instrument has a number or not, will have Bold and Underscored Text for its Serial Number (or "unknown number") to stand out. (Examples: A0100 and A0xxx [Unknown 350 Guitar Example.]) When one of these marks is new, I'll also keep it in bold underscored text in the following update, but I'll remove the marks in the update after that.

Instruments that are finished in any kind except Natural, White or Yellow will have their finish set in colored text, except for Black. Black instruments will use Bold Text, to stand out more clearly.

Model Trivia:

Both the 300 and 350 models are usually Mahogany-bodies and necked instruments, though we have 1 or 2 exceptions to the rule. They have typical Mosrite appointments; 24.5" scale length (Guitar,) 30" (or so, roughly speaking) Scale Length (Bass.) Mosrite Pickups. For these 300 and 350 models, these mostly have the rarer 1970s Mosrite Humbuckers that weren't (as far as I'm aware) available in other decades. (I could be wrong, I don't know the 1978 - 1992 models very well.)

300 models are 1-Pickup (in stock form) models. They came as Guitar and Bass. Few have shown up, though I don't think they'd be any more valuable than a 350 model in 2021. Basses had the pickup both in the Neck position, and Bridge position. Guitars seem to have only had the pickup in the Neck position, but the list is incomplete, yet.

350 models are 2-pickup models that came as Guitar and Bass. There are "Stereo" (2 cord output) and "Mono" (1 cord output) models of each Guitar and Bass, and it appears that Stereo models are more common than Mono models. The Mono models only seem to have been made between A0100 and A0185, and not all of those are Mono models.

Speculated # Section - 1 Guitar:

K0009: Natural. Pic saved. Vaguely appears to be K0009, but I can't tell for sure in the photo. Doesn't have its stock pickup installed at the moment. It has been drilled to have a Bridge Pickup, too. It has a Bill Lawrence pup in the Bridge, a Seymour Duncan P90 in the neck, and an extra knob. Owned by forum member "rtdreep," who has owned it since 1978 (roughly speaking.) He does have the stock pickup, though. The guitar was mentioned in the forum, here: viewtopic.php?f=4&t=7994

AB0036: Stereo, Blue. Photos and page saved. Has a Maple neck. Ad says the body's made of Alder. This finish may be original, since it looks old, and it looks like it aged like other 350s. This is the second Blue 350 I've seen; A0148 (a Guitar) is also Blue. https://reverb.com/item/34060236-mosrit ... blue-1970s Photos from 2016, before this instrument was for sale on Reverb, show this instrument without a Mosrite logo.

AB0xxx: Stereo, Lemon Yellow/Aged White Finish. Was on eBay in February 2011. Pics saved. Doesn't have Mosrite M Knobs (just like A0345 which is also Yellow,) and it appears that Mosrite used cheaper knobs late in the model run.

A0271, Stereo, Brown Burst. Pics and page archived. Sold by "hammondguy" on eBay on October 29, 2020 for $1,195. Has been refretted, and the zero fret is now stainless.
A0293, Stereo, Red Burst. Pics saved. A clear photo of it was posted on Facebook from "Blues Rock" in Hong Kong, and I saved the photo. This is highly likely to be the guitar I linked in the Reverb ad; the wood matches up. If it is the same guitar, they bought it without M Knobs, and added M Knobs later (which may or may not be accurate to how it was originally sold.) The older Reverb photos are barely legible, but I made out that they seemed to be A025? or A029?, judging by the closer photo. Reverb ad:
https://reverb.com/price-guide/guide/24 ... 0-1974-red
A0309, Stereo, "Walnut Burst" (probably a Brown Burst.) Had a nut instead of a metal string guide when it showed up in February 2014. I posted it years ago: viewtopic.php?f=27&t=6118

A0344, Stereo, Black. Nate Gibson's Guitar. Pics saved. Has been customized and repaired, and it has M Knobs. The pinstriping on it was done by Charlie Decker, the Armrest and Pickguard by Sarah here on the forum, and Evan Williamson worked on the crumbling binding. Also, I saved a photo of what's probably it, pre-customization, from Eastwood Guitars' site. I tried, and I was then able to make out the numbers as being "A0?44:" https://eastwoodcustoms.com/projects/mosrite-350/
A0345, Stereo, Yellow. Pics and page saved. Knobs are teardrop shaped. Listed on Reverb by Poway Jewelry and Loanon September 20, 2019. https://reverb.com/item/28163955-vintag ... ric-guitar

A0350: Stereo. Black or Forest Green. Pics saved. A seller called this finish "Forest Green." Owned by forum member GTSP (as noted in the second link below.) Photos saved from his Photobucket page. It looks Black instead of Green to me, but maybe it's just the lighting in Jayson's photos, since I vaguely remember this guitar being green. Serial # is according to Jayson.

Speculated # (Partial, or not) Section - 6 Guitars

Numbers in this section are as close as I could speculate, after looking at photos or by other speculation.

A0006? Stereo. "Light colored body wood." Seller gave number as "9000 V," which I suppose could have been read upside down. This is not confirmed, though. First mentioned here, by moaimen: viewtopic.php?p=71576#p71576
A0038: Stereo, Natural, stock. Belongs to Tim Brennan. Can be seen at his Facebook post, here: https://www.facebook.com/Tymguitars/pos ... 0711924953
A0134 or A0154: Mono, Red. Has a Moseley Vibrato. May be A0134, but I can't tell the one digit very well.
https://www.sheltonsguitars.com/2008/1- ... 08-08.html
A0291: Stereo, Brown Burst. It seems most likely to be A0291, judging from other Brown Burst guitars near this number and by how the 9 stamp appears on other guitars. This guitar has a Nut instead of its original String Guide. This is the guitar photographed on the side of this page, under the description for the 350 model:
https://reverb.com/p/mosrite-stereo-350-sunburst-1972
A0304: Stereo, "Bright" Sunburst (compared to the brown ones.) Appears to be A0304, but it's hard to tell. Knobs aren't the "M" type (but are possibly original.) Was apparently for sale from Detroit Guitar, since it's posted to their Pinterest page. https://www.pinterest.com/pin/552605816757739103/

Unknown #s - 14:

A0xxx: Stereo. Black. Owned by Lil' Jimmy Reed, and is customized; has "Lil' Reed" on the body and headstock. It may be somewhere over A0300, judging by the numbers of known Black 350s. Video from 2013: https://youtu.be/ZYc0CtwvItQ
A0xxx: Stereo, Brown. Was for sale on eBay on March 24, 2011. Photos have been saved.

A0xxx: Stereo, Natural. Doesn't have M Knobs. Pic saved. Body was heavily cut away to look more teardrop-ish. Found on Facebook, posted by Larry's Guitars. I think I can still see at least one number on it, but I can't quite tell what it is.
A0xxx: Stereo, Natural. Appears to be in the first 100, but I can't tell for sure if it's A0057, A0067, A0069 or A0075. Appeared in late 2020, from Jean-sebastien's saucisserie shop in Baie Des Sables, Canada.: https://reverb.com/item/37253942-mosrit ... -week-deal

A0xxx: Stereo, Brown Burst.. Pic saved. I found the photo on Pinterest, and followed the link; it was down. I found the original ad in the Wayback Machine, but most of the photos weren't saved.

Tym Brennan's Unknown # 350s;
A0xxx: Mono, Natural. Has a Mosrite Single Coil in the bridge.
A0xxx: Mono, Dark Sunburst. Has a Maple Ventures neck, a Mosrite single coil in the neck position, and a Mosrite stop-tailpiece screwed into a Moseley Vibrato Base Plate. I question why the baseplate's installed.

All of Tym's 350s can be seen here:

May not have a # anymore:

A0xxx: Stereo, Natural. Pics saved. Doesn't have M Knobs. Has a Bigsby and a Tune O Matic, and was refretted twice (so it may no longer have a number.) Pups were re-wound, too. Found on Facebook, posted by William R. Crabtree.
A0xxx: Stereo, Natural (or slightly more brown.) May have lost its # in a Refret (judging from photos) though I'm not certain if it did lose the #. Formerly owned by Will Speer (Will S on the forum) and was played in a 2007/2008 video from Rockongoodpeople. viewtopic.php?f=6&t=1942&p=19381#p19381

--------------

98 instruments are listed (or fewer, due to the unknown and speculation sections.)

5 300 Basses,
4 300 Guitars,

1 Speculated # 300 Guitar
1 Partial # 300 Bass,

1 No Number 350 Bass,
9 350 Basses,
2 Speculated # 350 Basses,

50 350 Guitars - 11 or 12 Mono, 38 or 39 Stereo.

1 350 Guitar with a partial #,
6 350 Guitars with speculated #s (1 of those being partial but not 100% clear,)
1 Guitar that's a Partsrite,

6 Unknown 350 Basses
13 Unknown 350 Guitars.

Finishes Accounted For:

Black - Shows up late in the model run. (Earliest known guitar is A0237, though I wonder if it's really 337, and the earliest bass is AB117 - which happens to currently be the highest # for a Stereo 350 Bass.)
Blue - 3 accounted for.
Brown.
Brown Burst.
Natural - This is the most common finish seen. About the first 60 seem to be Natural, though without each one individually accounted for, I can't say that for certain.
Red.
Red, Translucent. (A0065.)
Red Burst.
Sunburst - 1 accounted for, though it may not be an original finish. The guitar is a speculated (but highly likely to be) A0304.
Yellow - 2 accounted for. (1 mystery bass, and Guitar A0345.) Perhaps these are the only 2, and they were ordered at the same time.
White - 1 mystery # bass accounted for.

Also, Guitar A0350 was once described as "Forest Green," in the ad where forum member "GTSP" bought it. I'm not sure if it's really a Dark Green, or a Black finish.

A0266 seems to be a Translucent Brown or Translucent Butterscotch color, strangely enough.

I feel confident that the Black, Brown, Brown Burst, Red, and Red Burst instruments are all original finishes. The Yellow ones might also be original, since I've found two of them that look nearly the same.

I'm not so sure about the originality of the Blue ones, the Green/Black one, or the White one. If I had better pics of the Unknown # Blue one, I could more easily tell.

Re: Mosrite 300 and 350 Serial Numbers? (Guitar and Bass)

Postby 101Volts » Thu Oct 14, 2021 8:53 pm

Latest Updates:

15th October, 2021:

I'm surprised I missed this one, for having posted in the thread it was in after starting this Serial # thread. Forum Member "coanda" posted some photos of the Stereo wiring in his 350 Bass, but I don't know its Serial #. I tried looking, and I saw nothing. I saved the pics (even though they're "Photobucket" stamped now.)

Link to the thread: viewtopic.php?p=59353#p59353

14th of October, 2021:

One Guitar added to the speculated # section. Somehow, I missed adding it here before. This is a Stereo Brown Burst belonging to one Kenneth Ray West, and I can only tell a probable first digit, making it now known as a A03xx number.

29th of June, 2021:

A0266, Stereo 350 in some Brown/Natural/Butterscotch-ish color added. https://reverb.com/item/41559486-mosrit ... 1973-brown

Legend:

An instrument new to the list (or moved from an Unknown section) as of the day the list is updated, whether the instrument has a number or not, will have Bold and Underscored Text for its Serial Number (or "unknown number") to stand out. (Examples: A0100 and A0xxx [Unknown 350 Guitar Example.]) When one of these marks is new, I'll also keep it in bold underscored text in the following update, but I'll remove the marks in the update after that.

Instruments that are finished in any kind except Natural, White or Yellow will have their finish set in colored text, except for Black. Black instruments will use Bold Text, to stand out more clearly.

Model Trivia:

Both the 300 and 350 models are usually Mahogany-bodies and necked instruments, though we have 1 or 2 exceptions to the rule. They have typical Mosrite appointments; 24.5" scale length (Guitar,) 30" (or so, roughly speaking) Scale Length (Bass.) Mosrite Pickups. For these 300 and 350 models, these mostly have the rarer 1970s Mosrite Humbuckers that weren't (as far as I'm aware) available in other decades. (I could be wrong, I don't know the 1978 - 1992 models very well.)

300 models are 1-Pickup (in stock form) models. They came as Guitar and Bass. Few have shown up, though I don't think they'd be any more valuable than a 350 model in 2021. Basses had the pickup both in the Neck position, and Bridge position. Guitars seem to have only had the pickup in the Neck position, but the list is incomplete, yet.

350 models are 2-pickup models that came as Guitar and Bass. There are "Stereo" (2 cord output) and "Mono" (1 cord output) models of each Guitar and Bass, and it appears that Stereo models are more common than Mono models. The Mono models only seem to have been made between A0100 and A0185, and not all of those are Mono models.

AB0036: Stereo, Blue. Photos and page saved. Has a Maple neck. Ad says the body's made of Alder. This finish may be original, since it looks old, and it looks like it aged like other 350s.

AB0xxx: Stereo, Lemon Yellow/Aged White Finish. Was on eBay in February 2011. Pics saved. Doesn't have Mosrite M Knobs (just like A0345 which is also Yellow,) and it appears that Mosrite used cheaper knobs late in the model run.

A0271, Stereo, Brown Burst. Pics and page archived. Sold by "hammondguy" on eBay on October 29, 2020 for $1,195. Has been refretted, and the zero fret is now stainless.
A0293, Stereo, Red Burst. Pics saved. A clear photo of it was posted on Facebook from "Blues Rock" in Hong Kong, and I saved the photo. This is highly likely to be the guitar I linked in the Reverb ad; the wood matches up. If it is the same guitar, they bought it without M Knobs, and added M Knobs later (which may or may not be accurate to how it was originally sold.) The older Reverb photos are barely legible, but I made out that they seemed to be A025? or A029?, judging by the closer photo. Reverb ad:

A0344, Stereo, Black. Nate Gibson's Guitar. Pics saved. Has been customized and repaired, and it has M Knobs. The pinstriping on it was done by Charlie Decker, the Armrest and Pickguard by Sarah here on the forum, and Evan Williamson worked on the crumbling binding. Also, I saved a photo of what's probably it, pre-customization, from Eastwood Guitars' site. I tried, and I was then able to make out the numbers as being "A0?44:" https://eastwoodcustoms.com/projects/mosrite-350/
A0345, Stereo, Yellow. Pics and page saved. Knobs are teardrop shaped. Listed on Reverb by Poway Jewelry and Loanon September 20, 2019. https://reverb.com/item/28163955-vintag ... ric-guitar

A0350: Stereo. Black or Forest Green. Pics saved. A seller called this finish "Forest Green." Owned by forum member GTSP (as noted in the second link below.) Photos saved from his Photobucket page. It looks Black instead of Green to me, but maybe it's just the lighting in Jayson's photos, since I vaguely remember this guitar being green. Serial # is according to Jayson.

Speculated # (Partial, or not) Section - 6 Guitars

Numbers in this section are as close as I could speculate, after looking at photos or by other speculation.

A0006? Stereo. "Light colored body wood." Seller gave number as "9000 V," which I suppose could have been read upside down. This is not confirmed, though. First mentioned here, by moaimen: viewtopic.php?p=71576#p71576
A0038: Stereo, Natural, stock. Belongs to Tim Brennan. Can be seen at his Facebook post, here: https://www.facebook.com/Tymguitars/pos ... 0711924953
A0134 or A0154: Mono, Red. Has a Moseley Vibrato. May be A0134, but I can't tell the one digit very well.
https://www.sheltonsguitars.com/2008/1- ... 08-08.html
A0291: Stereo, Brown Burst. It seems most likely to be A0291, judging from other Brown Burst guitars near this number and by how the 9 stamp appears on other guitars. This guitar has a Nut instead of its original String Guide. This is the guitar photographed on the side of this page, under the description for the 350 model:
https://reverb.com/p/mosrite-stereo-350-sunburst-1972
A0304: Stereo, "Bright" Sunburst (compared to the brown ones.) Appears to be A0304, but it's hard to tell. Knobs aren't the "M" type (but are possibly original.) Was apparently for sale from Detroit Guitar, since it's posted to their Pinterest page. https://www.pinterest.com/pin/552605816757739103/

Unknown #s - 14:

A0xxx: Stereo. Black. Owned by Lil' Jimmy Reed, and is customized; has "Lil' Reed" on the body and headstock. It may be somewhere over A0300, judging by the numbers of known Black 350s. Video from 2013: https://youtu.be/ZYc0CtwvItQ

A0xxx: Stereo, Natural. Doesn't have M Knobs. Pic saved. Body was heavily cut away to look more teardrop-ish. Found on Facebook, posted by Larry's Guitars. I think I can still see at least one number on it, but I can't quite tell what it is.
A0xxx: Stereo, Natural. Appears to be in the first 100, but I can't tell for sure if it's A0057, A0067, A0069 or A0075. Appeared in late 2020, from Jean-sebastien's saucisserie shop in Baie Des Sables, Canada.: https://reverb.com/item/37253942-mosrit ... -week-deal

May not have a # anymore:

A0xxx: Stereo, Natural. Pics saved. Doesn't have M Knobs. Has a Bigsby and a Tune O Matic, and was refretted twice (so it may no longer have a number.) Pups were re-wound, too. Found on Facebook, posted by William R. Crabtree.
A0xxx: Stereo, Natural (or slightly more brown.) May have lost its # in a Refret (judging from photos) though I'm not certain if it did lose the #. Formerly owned by Will Speer (Will S on the forum) and was played in a 2007/2008 video from Rockongoodpeople. viewtopic.php?f=6&t=1942&p=19381#p19381

--------------

99 instruments are listed (or fewer, due to the unknown and speculation sections.)

5 300 Basses,
4 300 Guitars,

1 Speculated # 300 Guitar
1 Partial # 300 Bass,

1 No Number 350 Bass,
9 350 Basses,
2 Speculated # 350 Basses,

50 350 Guitars - 11 or 12 Mono, 38 or 39 Stereo.

1 350 Guitar with a partial #,
6 350 Guitars with speculated #s (1 of those being partial but not 100% clear,)
1 Guitar that's a Partsrite,

7 Unknown 350 Basses
13 Unknown 350 Guitars.

Finishes Accounted For:

Black - Shows up late in the model run. (Earliest known guitar is A0237, though I wonder if it's really 337, and the earliest bass is AB117 - which happens to currently be the highest # for a Stereo 350 Bass.)
Blue - 3 accounted for.
Brown.
Brown Burst.
Natural - This is the most common finish seen. About the first 60 seem to be Natural, though without each one individually accounted for, I can't say that for certain.
Red.
Red, Translucent. (A0065.)
Red Burst.
Sunburst - 1 accounted for, though it may not be an original finish. The guitar is a speculated (but highly likely to be) A0304.
Yellow - 2 accounted for. (1 mystery bass, and Guitar A0345.) Perhaps these are the only 2, and they were ordered at the same time.
White - 1 mystery # bass accounted for.

Also, Guitar A0350 was once described as "Forest Green," in the ad where forum member "GTSP" bought it. I'm not sure if it's really a Dark Green, or a Black finish.

A0266 seems to be a Translucent Brown or Translucent Butterscotch color, strangely enough.

I feel confident that the Black, Brown, Brown Burst, Red, and Red Burst instruments are all original finishes. The Yellow ones might also be original, since I've found two of them that look nearly the same.

I'm not so sure about the originality of the Blue ones, the Green/Black one, or the White one. If I had better pics of the Unknown # Blue one, I could more easily tell.

Re: Mosrite 300 and 350 Serial Numbers? (Guitar and Bass)

Postby 101Volts » Thu Oct 14, 2021 11:47 pm

Latest Updates:

15th October, 2021 Update 2:

Correction to the wrong number of guitars accounted for. Also made the accountability list near the end more clear.

Also actually included Kenneth Ray West's Brown Burst A03xx Guitar this time.

15th October, 2021:

I'm surprised I missed this one, for having posted in the thread it was in after starting this Serial # thread. Forum Member "coanda" posted some photos of the Stereo wiring in his 350 Bass, but I don't know its Serial #. I tried looking, and I saw nothing. I saved the pics (even though they're "Photobucket" stamped now.)

Link to the thread: viewtopic.php?p=59353#p59353

14th of October, 2021:

One Guitar added to the speculated # section. Somehow, I missed adding it here before. This is a Stereo Brown Burst belonging to one Kenneth Ray West, and I can only tell a probable first digit, making it now known as a A03xx number.

29th of June, 2021:

A0266, Stereo 350 in some Brown/Natural/Butterscotch-ish color added. https://reverb.com/item/41559486-mosrit ... 1973-brown

Legend:

An instrument new to the list (or moved from an Unknown section) as of the day the list is updated, whether the instrument has a number or not, will have Bold and Underscored Text for its Serial Number (or "unknown number") to stand out. (Examples: A0100 and A0xxx [Unknown 350 Guitar Example.]) When one of these marks is new, I'll also keep it in bold underscored text in the following update, but I'll remove the marks in the update after that.

Instruments that are finished in any kind except Natural, White or Yellow will have their finish set in colored text, except for Black. Black instruments will use Bold Text, to stand out more clearly.

Model Trivia:

Both the 300 and 350 models are usually Mahogany-bodies and necked instruments, though we have 1 or 2 exceptions to the rule. They have typical Mosrite appointments; 24.5" scale length (Guitar,) 30" (or so, roughly speaking) Scale Length (Bass.) Mosrite Pickups. For these 300 and 350 models, these mostly have the rarer 1970s Mosrite Humbuckers that weren't (as far as I'm aware) available in other decades. (I could be wrong, I don't know the 1978 - 1992 models very well.)

300 models are 1-Pickup (in stock form) models. They came as Guitar and Bass. Few have shown up, though I don't think they'd be any more valuable than a 350 model in 2021. Basses had the pickup both in the Neck position, and Bridge position. Guitars seem to have only had the pickup in the Neck position, but the list is incomplete, yet.

350 models are 2-pickup models that came as Guitar and Bass. There are "Stereo" (2 cord output) and "Mono" (1 cord output) models of each Guitar and Bass, and it appears that Stereo models are more common than Mono models. The Mono models only seem to have been made between A0100 and A0185, and not all of those are Mono models.

300 Models:

Speculated # Section - 1 Guitar:

K0009: Natural. Pic saved. Vaguely appears to be K0009, but I can't tell for sure in the photo. Doesn't have its stock pickup installed at the moment. It has been drilled to have a Bridge Pickup, too. It has a Bill Lawrence pup in the Bridge, a Seymour Duncan P90 in the neck, and an extra knob. Owned by forum member "rtdreep," who has owned it since 1978 (roughly speaking.) He does have the stock pickup, though. The guitar was mentioned in the forum, here: viewtopic.php?f=4&t=7994

AB0036: Stereo, Blue. Photos and page saved. Has a Maple neck. Ad says the body's made of Alder. This finish may be original, since it looks old, and it looks like it aged like other 350s. This is the second Blue 350 I've seen; A0148 (a Guitar) is also Blue. https://reverb.com/item/34060236-mosrit ... blue-1970s Photos from 2016, before this instrument was for sale on Reverb, show this instrument without a Mosrite logo.

Speculated #s - 2:

AB0047: Stereo, Brown. I'm not sure of the 4 that I read, but I'm more confident that there's a 7 at the end. - 2 Piece Neck. Pic and page saved. http://www.oldfrets.com/Mosrite.html

AB0xxx: Stereo, Lemon Yellow/Aged White Finish. Was on eBay in February 2011. Pics saved. Doesn't have Mosrite M Knobs (just like A0345 which is also Yellow,) and it appears that Mosrite used cheaper knobs late in the model run.
viewtopic.php?f=27&t=4063
AB0xxx: Stereo, White. Has the Radio Shack-type Knobs on it. I expect this is a late one. Shown in this Youtube video from user "Rusted Vacuum," but the bass was not played in the video: https://www.youtube.com/watch?v=ISR68ErQ_L8 UPDATE, 2021 - June - 5: Found 1 photo of the same bass, and saved it.

A0271, Stereo, Brown Burst. Pics and page archived. Sold by "hammondguy" on eBay on October 29, 2020 for $1,195. Has been refretted, and the zero fret is now stainless.
A0293, Stereo, Red Burst. Pics saved. A clear photo of it was posted on Facebook from "Blues Rock" in Hong Kong, and I saved the photo. This is highly likely to be the guitar I linked in the Reverb ad; the wood matches up. If it is the same guitar, they bought it without M Knobs, and added M Knobs later (which may or may not be accurate to how it was originally sold.) The older Reverb photos are barely legible, but I made out that they seemed to be A025? or A029?, judging by the closer photo. Reverb ad:
https://reverb.com/price-guide/guide/24 ... 0-1974-red
A0309, Stereo, "Walnut Burst" (probably a Brown Burst.) Had a nut instead of a metal string guide when it showed up in February 2014. I posted it years ago: viewtopic.php?f=27&t=6118
A0329, Stereo, Black. Has M Knobs, and has a Bigsby added. Once owned by Michael Marks. http://home.insightbb.com/~marksma/wsb/ ... 63768.html

A0344, Stereo, Black. Nate Gibson's Guitar. Pics saved. Has been customized and repaired, and it has M Knobs. The pinstriping on it was done by Charlie Decker, the Armrest and Pickguard by Sarah here on the forum, and Evan Williamson worked on the crumbling binding. Also, I saved a photo of what's probably it, pre-customization, from Eastwood Guitars' site. I tried, and I was then able to make out the numbers as being "A0?44:" https://eastwoodcustoms.com/projects/mosrite-350/
A0345, Stereo, Yellow. Pics and page saved. Knobs are teardrop shaped. Listed on Reverb by Poway Jewelry and Loanon September 20, 2019. https://reverb.com/item/28163955-vintag ... ric-guitar

A0350: Stereo. Black or Forest Green. Pics saved. A seller called this finish "Forest Green." Owned by forum member GTSP (as noted in the second link below.) Photos saved from his Photobucket page. It looks Black instead of Green to me, but maybe it's just the lighting in Jayson's photos, since I vaguely remember this guitar being green. Serial # is according to Jayson. Thanks for sharing the number.

A002x, Stereo, Natural Finish
http://www.mylespaul.com/threads/1970-m ... er.301797/
A03xx - Stereo, Brown Burst. Pics saved. Belonging to one Kenneth Ray West, and I can only tell a probable first digit, making it now known as a A03xx number.

Partsrite Section - 1:

No-Number "Super 350" Partsrite, Mono, Red - Pics and page saved, including 3 from the current owner. Has a 21 fret Sooner neck (originals are 22 fret,) and the neck appears to be Maple. It also doesn't have a solid rosewood fretboard. The headstock says "Super 350." Has one Volume Knob, and one Tone Knob. It has two unknown switches, near the Vol and Tone Knobs. It also has a Black Widow-sized pad on the back, which is on other instruments of Tony Hunt's. Currently owned by Pete Kenney.

If it's a Partsrite, if it was a more common guitar, I might not bother. But these 350s are so rare as it is, that I might as well.

Speculated # Section - 5 Guitars

Numbers in this section are as close as I could speculate, after looking at photos or by other speculation.

A0006, Stereo. "Light colored body wood." Seller gave number as "9000 V," which I think was likely read upside down by the eBay seller in 2004. This is not confirmed, though. First mentioned here, by moaimen: viewtopic.php?p=71576#p71576
A0038: Stereo, Natural, stock. Belongs to Tim Brennan. Can be seen at his Facebook post, here: https://www.facebook.com/Tymguitars/pos ... 0711924953
A0134 or A0154: Mono, Red. Has a Moseley Vibrato. May be A0134, but I can't tell the one digit very well.
https://www.sheltonsguitars.com/2008/1- ... 08-08.html
A0291: Stereo, Brown Burst. It seems most likely to be A0291, judging from other Brown Burst guitars near this number and by how the 9 stamp appears on other guitars. This guitar has a Nut instead of its original String Guide. This is the guitar photographed on the side of this page, under the description for the 350 model:
https://reverb.com/p/mosrite-stereo-350-sunburst-1972
A0304: Stereo, "Bright" Sunburst (compared to the brown ones.) Appears to be A0304, but it's hard to tell. Knobs aren't the "M" type (but are possibly original.) Was apparently for sale from Detroit Guitar, since it's posted to their Pinterest page. https://www.pinterest.com/pin/552605816757739103/

Unknown #s - 14:

A0xxx: Stereo. Black. Owned by Lil' Jimmy Reed, and is customized; has "Lil' Reed" on the body and headstock. It may be somewhere over A0300, judging by the numbers of known Black 350s. Video from 2013: https://youtu.be/ZYc0CtwvItQ
A0xxx: Stereo, Brown. Was for sale on eBay on March 24, 2011. Photos have been saved.

A0xxx: Stereo, Natural. Doesn't have M Knobs. Pic saved. Body was heavily cut away to look more teardrop-ish. Found on Facebook, posted by Larry's Guitars. I think I can still see at least one number on it, but I can't quite tell what it is.
A0xxx: Stereo, Natural. Appears to be in the first 100, but I can't tell for sure if it's A0057, A0067, A0069 or A0075. Appeared in late 2020, from Jean-sebastien's saucisserie shop in Baie Des Sables, Canada.: https://reverb.com/item/37253942-mosrit ... -week-deal
A0xxx: Stereo, Natural. It's a late model, since it has the cheaper knobs on it. Showed up in a video on Facebook, from Brian Edwards. https://www.facebook.com/brian.edwards. ... 6626059188
A0xxx: Stereo, Brown Burst.. Pic saved. I found the photo on Pinterest, and followed the link; it was down. I found the original ad in the Wayback Machine, but most of the photos weren't saved.

A0xxx: Mono, Dark Sunburst. Has a Maple Ventures neck, a Mosrite single coil in the neck position, and a Mosrite stop-tailpiece screwed into a Moseley Vibrato Base Plate. I question why the baseplate's installed.

A0xxx: Stereo, Natural. Pics saved. Doesn't have M Knobs. Has a Bigsby and a Tune O Matic, and was refretted twice (so it may no longer have a number.) Pups were re-wound, too. Found on Facebook, posted by William R. Crabtree.
A0xxx: Stereo, Natural (or slightly more brown.) May have lost its # in a Refret (judging from photos) though I'm not certain if it did lose the #. Formerly owned by Will Speer (Will S on the forum) and was played in a 2007/2008 video from Rockongoodpeople. viewtopic.php?f=6&t=1942&p=19381#p19381

100 instruments are listed (or fewer, due to the unknown and speculation sections.)

300 Models - Total of 10 (9 with Known #s: )

5 Known # 300 Basses,

4 Known # 300 Guitars,
1 Speculated # 300 Guitar.

350 Models - Total of 90 (68 with Known #s, 3 unknowns may be without #s: )

20 Basses:

10 Known # 350 Basses,

Finishes Accounted For:

Black - Shows up late in the model run. (Earliest known guitar is A0237, though I wonder if it's really 337, and the earliest bass is AB117 - which happens to currently be the highest # for a Stereo 350 Bass.)
Blue - 3 accounted for.
Brown.
Brown Burst.
Natural - This is the most common finish seen. About the first 60 seem to be Natural, though without each one individually accounted for, I can't say that for certain.
Red.
Red, Translucent. (A0065.)
Red Burst.
Sunburst - 1 accounted for, though it may not be an original finish. The guitar is a speculated (but highly likely to be) A0304.
Yellow - 2 accounted for. (1 mystery bass, and Guitar A0345.) Perhaps these are the only 2, and they were ordered at the same time.
White - 1 mystery # bass accounted for.

Also, Guitar A0350 was once described as "Forest Green," in the ad where forum member "GTSP" bought it. I'm not sure if it's really a Dark Green, or a Black finish.

A0266 seems to be a Translucent Brown or Translucent Butterscotch color, strangely enough.

I feel confident that the Black, Brown, Brown Burst, Red, and Red Burst instruments are all original finishes. The Yellow ones might also be original, since I've found two of them that look nearly the same.

I'm not so sure about the originality of the Blue ones, the Green/Black one, or the White one. If I had better pics of the Unknown # Blue one, I could more easily tell.
