Originally manufactured by Colt as a Model 1921 Thompson SMG, one of a number stuck in inventory due to sluggish sales; while today the Thompson is recognized as an American classic and one of the all-time finest "heavy metal" SMGs, at the time it was a novel, untested and expensive weapon, and few were willing to roll the dice. The U.S. Marine Corps was an early adopter, and the firm attempted to capitalize on the connection by adding "U.S. NAVY" markings to their 1921s, updating the features based on USMC feedback, and overstamping the "1921" to "1928" to match their newer model. According to Herigstad's "Colt Thompson Submachine Gun Serial Numbers and Histories" (page 1034), this particular Thompson was shipped to the Hall County Sheriff's Office in Grand Island, Nebraska at an unknown date, with serial numbers around this gun showing shipments between 1934-1936. Blade front sight on the Cutts-marked compensator and a folding Lyman rear sight, showing the signature cooling fins on the barrel, dual pistol grips and quick-detachable buttstock with a small "anchor" on the front. The left side of the receiver has the aforementioned "U.S. NAVY" model markings ahead of the 5-line address and caliber markings, with the Thompson "bullet" logo on top and the Auto-Ordnance address and 6-line patent markings on the right. The trigger group is numbered to match the receiver on the underside, with knurled selector ("FULL/AUTO" and "SINGLE") and safety ("FIRE" and "SAFE") levers. The internals are of the 1928 pattern, with the reduced spring and spring guide, and correspondingly heavier bolt assembly, with brass Blish lock and felt padded oiler. One stick magazine is included. Provenance: Hall County (Nebraska) Sheriffs Office; Private Collection

Excellent, with 97% of the original blue finish, showing bright edge wear, and minor spotting and handling marks. The barrel shows a darker tone than the receiver, and the witness marks are not aligned; it may be a replacement component. The furniture is very fine, with some minor scuffs and dings overall. Mechanically excellent.
