This is just a beautiful example of a professionally refinished, Colt Manufactured, Thompson 1921/1928 "US Navy" over stamp submachine gun. This specific submachine gun was original produced in the 1921 configuration, and later updated with 1928 improvements and over stamped with "U.S. NAVY MODEL OF 1928". This model came into being because of the lagging sales for the 1921 series of SMG and the fact that the USMC successfully used many of these New SMGs in Nicaragua, with the hope of improving sales to various Police and Government agencies. The basic difference between the original 1921 and 1928 configurations is that the latter has a slightly reduced cyclic rate of fire, they were always fitted with the "Cutts" compensator and the recoil spring and guide were replaced with a smaller improved version. These Thompson SMGs were probably one of the finest submachine ever produced because of their superior, all machined metal parts, tight tolerances and high reliability in the field. They were heavily used by the USMC early in WWII during all their island hopping campaigns. 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 specific weapon retains the distinctive Thompson features such as; the "Cutts" compensator on the end of the barrel, the short 10 1/2 inch barrel with cooling fins, the vertical front pistol grip, the detachable buttstock and the fully adjustable Thompson ladder rear sight that is graduated from 100-600 yards. The left side of the receiver is marked "MODEL OF 1921" with the "U.S. Navy " markings being over stamped above the original model markings and the number "1" being over stamped on the number "8". The serial number "5862" is stamped below the marking block and the matching serial number (5862) is also stamped on the rear, underside extension of the trigger housing/lower receiver group. The left, rear side of the receiver it is marked "THOMPSON SUBMACHINE GUN/CALIBER .45 AUTOMATIC COLT CARTRIDGE/MANUFACTURED BY COLT'S PATENT FIRE ARMS MFG. CO./HARTFORD, CONN. U.S.A.". The right side is marked with the five lines of dates along with the two line "AUTO-ORDNANCE CORPORATION, NEW YORK U.S.A". The top of the receiver and is marked with the famous "Thompson/Bullet" logo. They all have a distinctive deep rich blued metal finish with the bolt remaining in the white with excellent deep dark brown walnut, fore grip, pistol grip and buttstock..This lot does not come with any magazines or additional accessories, however they are easily located on the secondary market.
