This is an example of an M1A1 SMG that was produced in the 1970s by the Auto-Ordnance Corp. in West Hurley, NY. This example is a direct copy of the original WWII version with all the wartime features such as a stamped "L" type fixed rear sight with sight protectors, horizontal walnut forearm, fixed buttstock and side-mounted cocking handle. It has no cooling fins on the barrel and no compensator. Additionally, the entire bolt mechanism was redesigned for faster production that includes a one-piece bolt with a simple firing pin mechanism. The receiver is marked: "THOMPSON SUBMACHINE GUN/CALIBER 45 M1/NO. M481A", and the right side is marked: "AUTO ORDNANCE CORPORATION/WEST HURLEY NEW YORK U.S.A." The lower trigger housing is marked: "AUTO/SINGLE" and "FIRE/SAFE". This wonderful SMG comes with its original matching serial number shipping box, the shipping document, advertisement paper, and one 20-round magazine.
