Thompson 1928 A1 Bridgeport with Original Bridgeport Drum. Also comes with stick magazine. Late smooth barrel with Cuts compensator and excellent bore Original sling. There are no US proofs and the rear sling swivel is mounted on the top of the stock indicating British lend-lease use. AA stamp on butt indicates rework by Allegheny Arsenal. Upper and lower numbers are matching which is unusual for these guns. A few areas of tiny pitting do not detract. Interesting gun for $24,750.
