Federal Laboratories Incorporated Brochures
Federal Laboratories was the sole distributor of the Thompson Submachine Gun in the 1930s. In the late-1939 to early-1940 time frame, Auto-Ordnance Corporation revoked their exclusive rights. This led to versions of the 1938 catalogue (number 57A) and the 1939 catalogue (number 62) with the sole distributor phrase and a version of the catalogue with that blacked out. Below are samples of catalogue numbers 33, 34, 57A & 62.
