This is a scarce example of a World War II M1928A1 Thompson submachine gun manufactured by the Savage Arms Company under license from the Auto-Ordnance Company, with an "S-" prefix serial number, and was either part of a number of Thompsons later imported from overseas back into the United States by Numrich Arms Corporation or assembled from their massive stockpile of genuine surplus Thompson components, with Numrich's "N.A.C." suffix stamped after the original serial number. The importation of live machine guns into the United States for civilian ownership was legal at this time in the 1950s-1960s. Features a 10 1/2 inch barrel with cooling fins, an Auto-Ordnance Cutts compensator, fully adjustable Lyman rear sight, walnut forend, pistol grip, and detachable buttstock. "TOMMY GUN" stamped on top of the receiver. The underside of the lower trigger housing is numbered "S-187271". Includes a black FBI style hard case with keys, two 50-round "Type L" drums, three 15-round stick magazines, two 30-round stick magazines (seven total magazines accompany the lot), Kerr NO BUCKL tan canvas sling, cleaning rod, extra recoil spring, extra buffer pilot, and extra breech oiler.
