This is a scarce example of a World War II M1928A1 Thompson submachine gun manufactured by the Savage Arms Company under license from the Auto-Ordnance Company, with an "S-" prefix serial number. Blade front sight on the Auto-Ordnance/Thompson marked Cutts compensator, Lyman folding ladder rear sight, with the "US MODEL OF 1928A1", "RLB" and "GEG" on the left side of the receiver, Bridgeport address and eight-line patent markings on the right, and "TOMMY GUN" on top. A set of British proofs are also present, with tonnage marks on the barrel and faint "crown" proofs on top of the receiver and charging handle. While not documented, the combination of these proofs and the positioning of the sling swivels (left side of front pistol grip and top of buttstock) suggest transfer to Great Britain for military use during World War II as part of Lend-Lease, and later return to the United States. Internals are 1928 pattern, with "S" marked bolt and Blish lock, and an unmarked charging handle, spring guide and oiler. The trigger housing is numbered to match the receiver, with lightly knurled control switches. Fitted with grooved pistol grips, a quick-detach buttstock, modified as previously noted, and a green canvas sling. Included with the lot are one Type "C" 100-round drum magazine, two Type "L" 50-round drum magazines, three stick magazines, three canvas drum pouches (one "C" and two "L"), and a manual.
