This is a very nice condition Thompson Bridgeport model 1928AC .45 caliber submachinegun transferable. This will come with the FBI case, one Crosby 50 round drum and four 30 round magazines, of which one is a Seymour, one a Bridgeport and the other two standard US.

This is a rare variation with numbers matching on the upper and lower receivers.

 

Price: $28,950
 

Information on the 1928AC Bridgeport:
An interesting variation of the Auto-Ordnance, Bridgeport produced M1928A1 Thompson that has been observed, are those Thompsons that have had the U.S. designation ground off and the A1 mark overstamped to read AC. Many of the guns documented had been refurbished, and fitted with the smooth barrels and the “L” style fixed rear sight. Many, but certainly not all, of these guns so altered were in the 150,000 to 152,000 serial number range. A letter X was added as a suffix on the serial numbers of many of these guns. A few other examples of these “1928AC” Thompsons documented were fitted with the finned barrel and Lyman adjustable rear sight. A small number of these Thompsons had their original military horizontal foregrip replaced with the early style vertical foregrip. It is believed that these were guns that had been purchased from the government by the Auto-Ordnance Corporation and refurbished in order to be sold to law enforcement agencies after they were surplused. The Numrich Arms Corporation also removed U.S. markings from 1928 and 1928A1 model Thompsons they sold in the 1950’s.

Interestingly, some of the AO “1928AC” overstamped Thompsons did not have Army Inspector of Ordnance (AIO) acceptance stamps on them, but were stamped with the Ordnance “wheel” acceptance mark. While other examples of these guns had no government inspector or acceptance stamps at all, suggesting that they were never inspected or accepted by the U.S. Government. Perhaps these guns were contract overruns or assembled from parts that remained after the government contracts were filled. However, no documentation could be located that could prove or disprove this theory.

A Treasury Department IRS Form dated June 30, 1944 reveals that two Auto-Ordnance manufacture U.S. 1928A1 Thompsons with an X suffix added to the serial numbers were sold to a Massachusetts police department that year. The U.S. was ground off and the letter C over stamped on the 1 on both of the guns. Please note that the war didn’t end until the 15th of August 1945. All of the 1928 “AC” guns documented were originally manufactured by the Auto-Ordnance Corporation’s Bridgeport factory, and in almost every case had an AO prefixed serial numbered frame, although most of the frame/receiver numbers were mis-matched. The serial numbers located on the frames of these weapons also had the letter X added to them.
