Here's what Frank Iannamico has to say about it, and he's as close the M1?m1A1 TSMG guru as you can get. About the best you can hope for is to extrapolate an approximate date of manufacture based on production figures. Lloyd, AFAIK there is no comprhensive list of serial number/month/year for the Thompson M1/M1A1 submamachineguns. You might want to try the Thompson Collectors Association at PO Box 8710, Newark, Ohio, 43055 USA. I know of no other source of info on service history, and none on the M1A1. I think that for the time being you are not going to be able to find out anything about your TSMG's service history.įor the Model of 1921 TSMG around 15,000 or so serials are listed in "Thompson: The American Legend". However, I just consulted the 4 volumes in my library and I see that there are no automatic weapons listed there.Įven if the service was still available the chances of a hit on it are very, very slim. The next best sources are the published serial number books that SRS founder Frank Mallory sold years ago. I hope he resurrects it, but my sources tell me that is unlikely. Charlie Pate bailed out of the operation last year and the guy now running it has apparently determined that the online lookup feature was not something he wanted to continue.
Don't count on the SRS online service re-appearing anytime soon.
