This is a very close copy of the Finnish Soumi M31 SMG that was manufactured by the John R. Stemple Company in Groveport, Ohio, chambered in the popular 9 mm Luger cartridge. It is a blow-back operated SMG with a heavy round steel (tubular) receiver, machined bolt, fixed firing pin, with a heavy perforated steel 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 receiver is roll marked: "JOHN R. STEMPLE, GROVEPORT, OHIO MODEL 76/45 S/N/ 753" with the lower left side of the magazine housing marked: "STG Circle logo with a "B inside a Triangle/BRP CORP./STEMPLE 76/45". It is fitted with a 9 mm barrel and bolt. It has a large tangent rear sight mounted on top of the receiver graduated 1-5 (100-500 yards) and a fixed front sight. It has a slide safety in front of the trigger guard bow. It is fitted with a European beech wood stock (like the Finish M39s) with a blued steel buttplate with sling swivels mounted on the sides. It does use the standard SOUMI M31 SMGs magazines which are available on the secondary market.

Very fine with 99% of the parkerized finish overall. The hardwood stock is also in excellent condition showing no handling marks. The gun looks like it's in like new unfired condition with no wear or firing marks on the bolt face.
