This is an exceedingly rare example of a Thompson Model 1929 SMG that was manufactured by the BSA factory in England. This example is serial number "2" out of a estimated 10-15 examples actually manufactured. This SMG was licensed by the Auto-Ordnance Corp. to the BSA Shirley factory and was a redesign of the famous 1928 model intending it to be manufactured in England with the intent of generating sales in Europe and the Far East. It has a somewhat different overall design and configuration based on what the BSA factory felt needed to be corrected. It was also made in several different calibers, namely the standard 45 ACP, 9mm Luger, 9mm Bergman-Bayard, 7.63 Mauser, 7.65 Luger with some also reported in 7.62 Tokarev, obviously with specific countries in mind that used those cartridges. Basically it has just a slightly redesigned upper receiver that retains the original barrel, compensator and forend with the rear of the receiver machined flat on the end. This was to accommodate a completely redesigned trigger housing and stock assembly. This new trigger housing did away with the standard 1921/28 designed pistol grip and instead has a straight trigger housing with the trigger moved towards the rear. It also has a completely new redesigned magazine release and selector switches on the front left side. Based on the redesign of the trigger housing, one of the most visible redesign changes is the use of a British Enfield rifle stock and pistol grip. In this example the Enfield buttstock, is attached to a rear plate on the trigger housing with a vertical pistol grip fitted/added in the pistol grip area on the underside of the stock. Later models did away with the additional pistol grip and just used the standard Enfield stock. It still retains the folding rear Thompson tangent sight and uses the standard stick or drum magazines, (neither one are included with this lot). The left side of the receiver is marked: "MODEL OF 1929/No.2" and farther back it is marked: "B.S.A. THOMPSON SUBMACHINE GUN./CALIBRE 45 AUTOMATIC COLT CARTRIDGE.". The lower front edge of the trigger housing is marked "SINGLE and FIRE". The right front side of the receiver is marked with: "THOMPSON PATENTS", followed by 9 different Patent numbers.
