Item Description

This Chester County Armory listing is for an original Auto-Ordnance Thompson Model 1928AC .45acp fully transferable factory sub machine gun. 

Made in Bridgeport, CT, this Thompson Model 1928AC is in excellent overall condition. Both the upper receiver and the lower receiver trigger group are correctly serial number matched.  Mechanically, all mechanisms function approriately and there is only limited wear noted on the internal parts. The metalwork is all in excellent condition, and notes no marks other than normal handling marks in the finish consistent with the age of the firearm.

The wood furniture is also in superb condition with only a single minor chip noted on the bottom of the pistol grip (see photo). The horizontal forend and stock are in excellent condition, as well, with no cracks, scratches, or chips, and only a few minor surface dings that are so small they do not show up on photos well enough to document. 

The exterior parkerization of the metal is also in great,  age-appropriate condition, with only minor cosmetic surface handling marks in the metalwork. It does appear that the original blued barrel (which was common to the M1928AC with a parkerized receiver) was at some point coated in a gray finish to better match the parkerized receiver. There are few spots of wear noted in this finish on top of the barrel (where it was probably stored) and a few marks under the Cutts compensator (see photo). The stock buttplate was also finished in this same manner, and shows some wear in the finish, as well. 

This fully transferable Thompson sub machine gun will come with one original Auto-Ordnance Bridgeport Type L 50rd drum magazine, a 30rd stick magazine, and an original WWII era US marked military sling for the Thompson.

This machine gun is currently on a Form 3 for easy transfer.  The NFA paperwork lists "Auto-Ordnance" as the manufacturer, and "28AC" as the model.
