This is an example of an H&R produced Reising Model 50 submachine gun chambered in 45 ACP. The Reising Model 50 saw limited use by the U.S. Marines in the Pacific as a substitute for the M1 Thompson, eventually being replaced by the M3/M3A1 SMGs. Many of these weapons were transferred to various law enforcement agencies in the late 1940s and early 1950s. They were a blow-back operated designed which had the cocking handle located in a cutout on the underside of the forend. This is a late model as the markings are read from the left side of the receiver, from the front to the back with: "MODEL 50 H&R REISING --- CAL 45/HARRINGTON & RICHARDSON ARMS CO./WORCHESTER MASS.U.S.A. PAT PENDING". The right rear side of the receiver is marked: "SAFE/SA/FA", for safe, semi-automatic and full automatic. They have a short, finned barrel to aid in cooling, similar to the Thompson, with an integral compensator/muzzle break on the end. They have a fixed front sight with a stamped sheet metal rear sight that is adjustable for elevation only. They have a one-piece pistol grip walnut stock with a flat sheet metal buttplate on the end with a parkerized finish on all the metal parts. It comes with three original H&R marked blued Model 50 magazines.

Very fine with 85% of its blued finish overall showing general light wear and blue loss on the exposed metal surfaces. The stock is in very good condition with a dark oil finish showing handling and scratches on the sides overall. The right side of the stock has two holes, one at each end like it was at one time mounted on a display board.
