This is a fine restored example of a fully automatic Colt Auto Ordnance Thompson 1921/1928 US Navy over stamp submachine gun. This specific submachine gun was originally produced in the 1921 configuration, and later over stamped with "U.S. NAVY MODEL OF 1928". This model came into being because of the lagging sales for the 1921 series of sub machine gun, and the fact that the USMC successfully used many of these new sub machine guns in Nicaragua, the Auto Ordnance company began to remark their inventory with the intent of piquing sales interest 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. These Thompson sub machine guns were probably one of the best machined and hand fitted submachines ever produced. They all have a distinctive blue metal finish with the bolt remaining in the white with excellent deep dark brown 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 slide together like glass. This specific weapon still has all the traditional and distinctive Thompson features recognizable from all the gangster and WWII movies. The features consist of: the Cutts ported compensator on the end of the barrel, the short 10 1/2" barrel with cooling fins, the vertical pistol grip, the detachable buttstock and the fully adjustable Thompson/Lyman ladder rear sight that is graduated from 100-600 yards. The left side of the receiver is marked "U.S. NAVY/MODEL OF 1921" with the "8" dated over stamped on "1" in 1921, with the serial number 13163 below the marking block, (with the matching serial number 13163) on the flat behind the pistol grip area. The left rear portion of the receiver 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 patent dates along with the two line "AUTO-ORDNANCE CORPORATION, NEW YORK U.S.A". The top of the receiver is marked with the "Bullet" logo with "THOMSPON" inside. As noted, this specific sub machine gun is complete with a black FBI type carrying/storage case that also houses: two original Thompson "L" type 50 rd drum magazines, three original blued twenty round stick magazines made by the "SEMOUR Products Company" and an original brass cleaning rod. NOTE: This is a fully transferable NFA Class III Firearm currently on a Form 4. You are required to check your state and/or local laws as to whether or not you may own this. This weapon can be transferred to a Class III dealer at no charge. Buyer pays all other transfer fees and stamps.

Fine with most of the restored blued finish overall with nice clear, sharp markings and proof marks. The buttstock, pistol grip and vertical fore grip are all in excellent condition with almost no handling marks with a nice hand rubbed oil finish on the wood. The various magazines are all in excellent to like new condition. The storage case is also in very good plus condition overall some very minor edge wear in a couple of places with both ends of the lower section of the case having lost some of the leatherette cover with all the brass corner protectors and hinges intact. A very nice example of a Colt 1921/28 US Navy Overstamp sub machine gun that is fully transferable.
