Annihilator Posted July 14, 2014 Report Share Posted July 14, 2014 A few years ago i found a Thompson spare barrel which i believe is a 1921 barrel as it has no compensator threads, but the ring sight had been removed already. It is in a bad condition but has definitely a different shape that the one shown on the 1921 Thompson on the picture below. Any ideas on this ?

Sandman1957 Posted July 14, 2014 Report Share Posted July 14, 2014 Can you include a photo of the entire barrel? Is it the same length as the bottom barrel? I have seen a 1921 that may have this pattern. Link to comment Share on other sites More sharing options...
bug Posted July 14, 2014 Report Share Posted July 14, 2014 (edited) Are there any markings on it? Back off a little, too if you retake the photo. That picture is hard to look at... Edited July 14, 2014 by bug Link to comment Share on other sites More sharing options...
Arthur Fliegenheimer Posted July 15, 2014 Report Share Posted July 15, 2014 Never seen a Colt/Remington 1921 TSMG barrel where the threads do not extend beyond the vertical foregrip. That being the case, it doesn't appear that this barrel was a Colt TSMG production barrel made in 1921/1922 Link to comment Share on other sites More sharing options...
giantpanda4 Posted July 15, 2014 Report Share Posted July 15, 2014 Looks like the wrong number of fins too - maybe just the angle of the picture but the gun shows the mount bolt on a different fin than the wear on your barrel. JMHO. Link to comment Share on other sites More sharing options...
TD. Posted July 15, 2014 Report Share Posted July 15, 2014 I would like to know more about the 1921 Thompson with the vertical fore grip and interesting sling swivel. Link to comment Share on other sites More sharing options...
Annihilator Posted July 15, 2014 Author Report Share Posted July 15, 2014 I will post some additional pictures. Yes, the number of fins is not the same and that was my question. I cannot see any markings as it was found in a bad condition and i have cleaned it up. The Thompson on the picture is a 1921 french contract with Bertier sling swivels.

Annihilator Posted July 16, 2014 Author Report Share Posted July 16, 2014 (edited) Here are some more pictures. The barrel is 10 inches long. No visible markings, just the index mark Edited July 16, 2014 by Annihilator Link to comment Share on other sites More sharing options...
halftrack Posted August 19, 2019 Report Share Posted August 19, 2019 Going through some old threads, any conclusion on the origin of this barrel? Link to comment Share on other sites More sharing options...
mnshooter Posted August 20, 2019 Report Share Posted August 20, 2019 (edited) The texture of the machining says homebuilt job, possibly on a M1 barrel, which maybe also removed any proof markings. If this was a M1, the straight front shank, extending back to the first fin, removing any original taper, is also a sign of home shop work.Would have to assume whoever did the work didn't have an original finned barrel for reference.

BillyDixon Posted August 20, 2019 Report Share Posted August 20, 2019 back in 1970- 1980s i cut fins in about 100 m1 thompson barrels for dave cumberland, akaold west scrounger.. if i rember he bought several hundred at a military auction. i think he paid 1.oo each,perhaps this is one of them, boy those were the days, just sayn Link to comment Share on other sites More sharing options...
