Description:

This is an excellent example of a Colt/Auto Ordnance Model 1921 submachine gun with the 1928 U.S. "Navy" overstamp markings. Regardless of the configuration, these Thompson SMGs were probably one of the finest submachine guns ever produced, that had superb machining and hand fitted parts. They all have a distinctive deep rich blue metal finish with the bolt in the white. Fitted with a vertical walnut, fore grip, pistol grip and buttstock. If you ever have a chance to disassemble one of these weapons you will be amazed at how well they were made, the parts just slide together like glass. This model still retained the distinctive Thompson features, easily recognizable in the various WWII and gangster movies such as; the short 10 1/2 inch barrel with cooling fins, the ported Cutt's barrel compensator, the vertical pistol grip, the detachable buttstock, and the fully adjustable Thompson ladder rear sight, graduated from 100-600 yards. The left side of the receiver is marked "U.S. Navy/MODEL OF 1921" with the number "8" over stamped on top of the number "1" in 1921, over serial number "10033". 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." The top of the receiver is marked with the "Bullet" logo with "THOMPSON" inside. The lower trigger housing is also correctly stamped with the matching serial number of "10033". 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. This specific Thompson submachine gun is complete with five fifty round drum magazines, two with canvas carrying cases and two of the very rare 100 round drum magazines, one with a canvas carrying case six 20 round stick magazines and two (2ea) 30 round stick magazine in a canvas carrying case. As listed by serial number in Volume 1 to Herigstad's "Colt Thompson Submachine Gun Serial Numbers & Histories," this Thompson was originally sold to the Indiana State Police, was later acquired by J. Curtis Earl of Phoenix, Arizona in 1969 and was formerly part of the Peter G. Kokalis collection of "Soldier of Fortune" magazine fame (page 912).

Rating Definition:

Excellent with 95% plus of the original Colt blued finish with light edge wear visible with minor blue loss on the upper underside area of the lower trigger housing above the rear pistol grip. The wood components are all in excellent condition with a nice straight grained figure throughout with only a couple minor handling marks on the sides of the buttstock. Mechanically excellent. One of the "C" magazines is repaired on the front guide rib, otherwise various magazines and canvas pouches are all in excellent condition. A really super nice high condition Colt/Thompson 1921/28 Navy Over stamp SMG.
