NPS museum catalog record for a Colt-made Thompson marked "U.S. NAVY MODEL OF 1928/13159," with a 20-round box magazine and Cutts compensator, made about 1928 and donated by Savage Arms Co. in 1979. The catalog photograph is not stored here.

The catalog describes the 1928 model as "Basically a M1921 modified for the U.S. Navy," with a horizontal foregrip and a heavier bolt. The gun is a military configuration. It is shown here as the Model 1928 type that federal agencies bought in the 1930s, without implying any crime history for this gun.
