This is a scarce example of an originally unfinished WWII 1928A1 Thompson submachine gun initially manufactured by the Savage Arms Company under license from the Auto-Ordnance Company and then completed by the Numrich Arms Company. In the early 1970s, George Numrich acquired a huge amount of WWII spare parts and partially completed Thompson submachine receivers and barreled receiver from both the Auto-Ordnance and Savage companies and at the same time imported a large numbers of Thompsons from overseas. Using that stock pile of parts, he completed/assembled all the remaining stock of receivers and barreled receivers from the two companies into complete 1928 Thompson SMGs and then reworked those that were imported while at the same time manufacturing new semi-automatic 1927 rifles. He was required to remark the receivers he completed with his "NAC" serial numbering, hence the current serial number "S-527235 NAC", and sold them as commercial weapons. The receiver is marked with "MODEL OF 1928 A1/NO. S-527235 NAC" and farther back "THOMPSON SUBMACHINE GUN/CALIBRE .45 AUTOMATIC CARTRIDGE". It still retains its original late production short pattern 10 1/2 inch barrel without any cooling fins, a late commercial model Thompson/Auto-Ordnance "CUTTS" marked compensator, horizontal forend, fully adjustable Lyman rear sight, and a detachable buttstock. The obverse is marked in two-lines "AUTO-ORDNANCE CORPORATION, BRIDGEPORT CONNECTICUT USA". The top of the receiver is stamped with the "Auto-Ordnance/Thompson Bullet" logo. The underside of the lower trigger housing is correctly numbered and matching serial number (S-527235 NAC) to the receiver. It has a dark gray parkerized receiver and a matte blued trigger housing and barrel assembly. It is fitted with the correct walnut forend, pistol grip and buttstock. This Thompson SMG is complete with three 20 round stick magazines and one drum magazine.
