British Small Arms Model 1926 & 1929 Thompson Submachine Gun,The BSA Model 1929 Thompson was a license built variant of the Thompson Submachine gun produced by British Small Arms.  The submachine gun was manufactured for the purpose of export, thus they were produced in a wide variety of calibers including .45acp, 9mm para, 9mm Bergmann Bayard, 7.63 Mauser, 7.65 Luger, and 7.62 Tokarev. Major changes to the Thompson design included a redesigned trigger housing and trigger assembly, a traditional rifle stock based on that of the Lee Enfield rifle, and later with the Model 1929 a pistol grip.  Unfortunately the BSA Thompson failed to garner many buyers, and as a result very few were produced. -- source link
