This is a professionally restored example of a fully automatic Colt Model 1921 AC Thompson submachine Gun. This particular machine gun is a mid late production model as only 15,000 were manufactured in total with almost all of the later converted into the M1928A1 configuration. The Colt/Thompson SMGs were the high mark in submachine gun manufacturing. These were true works of art in that they were beautifully machined and hand fitted making them function beautifully. The receiver is marked "MODEL OF 1921/3151" along with the standard five-line factory markings: "THOMPSON SUBMACHINE GUN/CALIBRE 45 AUTOMATIC COLT CARTRIDGE/MANUFACTURED BY/COLT'S PATENT FIRE ARMS MFG. CO./HARTFORD CONN. U.S.A." The right side is marked "AUTO-ORDNANCE CORPORATION/NEW YORK U.S.A." followed by the standard five-line patent dates. The matching trigger housing is marked: "FULL-AUTO" and "SINGLE" along with "FIRE" and "SAFE" and is serial numbered "3151" on the underside. This model is an "AC" version which identifies it as a standard grade with the patented "CUTTS" compensator on the barrel. It also has the distinctive finned barrel, fully adjustable Lyman tangent rear sight with sight protectors, the walnut vertical fore grip, and the detachable walnut buttstock with the butt trap which holds an original Thompson oiler. The gun is complete with 5 stick magazines, 1 50 round drum magazine, and 3 manuals. This weapon is documented on page 332 in the excellent book "Colt Thompson Submachine Gun/ Serial Numbers" by Gordon Herigstad as being in the original Donald Cheney collection, Bridgewater NH, subsequently sold to Dr Nyberg Jr. It was then offered for sale in the winter of 2012 and then was again inspected in Feb 2013.

Very fine as professionally restored with an attractive blue finish with clear sharp/distinct markings overall. The wood components have also been restored matching the original Colt factory finishes very nicely.
