This is a very close copy of the Smith & Wesson M76 submachine gun chambered in .45 ACP manufactured by John R. Stemple in Groveport, Ohio. Similar in design the British STEN and Swedish M-45 submachine guns. It is a blowback operated SMG with a round sheet metal tube receiver, machined bolt, fixed firing pin, and the barrel held in place via a perforated barrel jacket/barrel nut. This design is very convenient as the barrel jacket can be unscrewed so that you can quickly replace the barrel or even change it to another caliber. The magazine housing is marked "M76/45 JOHN R. STEMPLE/GROVEPORT OH./SN1107". Fixed front and rear sights, with a rubber covered folding wire frame type stock. It only has a notch/cutout on the right side of the receiver tube that acts as a safety to hold back the bolt handle. Magazine is absent.

Excellent with 99% of the gray parkerized finish overall that is like new maybe having been test fired only. A very nice, short, compact SMG. Note: This weapon is a National Firearms Act (NFA), fully transferable Class 3, which is registered with the Bureau of Alcohol, Tobacco, Firearms and Explosives, (BATFE) under the provisions of 18 U.S.C. Chapter 44 and 27 CFR part 478.
