Purchased from Nassau County by Joe Miller (Miller’s Guns) Stroudsburg PA 1980 Purchased by Roger A. Cox (Author) Thompson Submachine Gun 1986, Law Inforcement Ordanance Co GA 8/2/86 Purchased by J Cor. June 30,1988 Purchased by NFA Sales 2020 This model came into being because the original Model 1921 SMG had a fairly high rate of fire (approximately 800 rds/min) and the military requested a slower more manageable rate of fire in the 600-700 rds/min range. The USMC had also been successfully using many of these weapons in the China and Nicaragua, so the Auto Ordnance company decided to convert the 1921 models to the slower cyclic rate of fire and remark their inventory with the intent of developing a new model (the U.S. Navy Model of 1928) meeting the military requirements and to help improve lagging sales and pique interest with police and government agencies. The basic difference between the original 1921 and 1928 configurations is that they increased the weight of the actuator, to reduce the cyclic rate of fire and also modified the firing pin assembly. The right side is marked with five lines of patent dates along with the two-line "AUTO-ORDNANCE CORPORATION/NEW YORK, U.S.A". The left rear side of the receiver is marked: "THOMPSON SUBMACHINE GUN/CALIBRE .45 AUTOMATIC COLT CARTRIDGE/MANUFACTURED BY/COLT'S PATENT FIRE ARMS MFG. CO./HARTFORD, CONN. U.S.A."
