# U.S. Submachine Gun Thompson Model 1921 .45ACP, SN 11867 (Springfield Armory NHS, SPAR 1546)

Canonical: https://mobfiles.org/items/nps-spar-1546-thompson-m1921/

NPS museum catalog record for a Colt-made Model 1921 Thompson, which the catalog says was manufactured between 1 and 4 April 1922 and transferred to the museum on 27 April 1960. The catalog photograph is not stored here.

The catalog quotes the museum's exhibit label: "Recalling the Prohibition era, the Thompson submachine gun ... represents the fully automatic weapons which continue firing as long as the trigger is pulled." It also cites the Armory's 1922 annual report: "The Thompson Sub-Machine Gun was tested."

The record carries a "STOLEN WEAPON ALERT" reference that this archive has not read in full. Much of the catalog's notes quote commercial collector sources, and only the catalog's own fields and the Armory annual report are cited here. This gun has no crime history in the record; it illustrates the model.
