This is a very nice example of a WWII General Motors M3 SMG. These weapons were developed circa 1941-1942 as a wartime substitute for the Thompson M1928 SMGs. The majority of these weapons were converted to the "A1" standard after 1944, however, this example remains in its original configuration, with the cocking handle on the right side with its original combination safety/dust cover. It has the fixed front and rear sight on top of the receiver. The left side of the magazine well is marked "SUB-MACH GUN/CAL. 45 M3" over the Guide Lamp marking and "Crossed Cannon/ U S NO 0025456". It is also marked "G.L. C153432" on the underside of the trigger cover and "B-301456-4 / BGR-GL" on trigger guard. The underside of the pistol is scribed via an electric pencil "MD ORD / McHNY ILL" and the lower front area is scribed "SN #1012". It has a telescoping wire stock and comes with three original 30 round stick magazines.
Fine as remarked with 75% of the parkerized finish overall. 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.
