A tank with real innovations
Developed in 1928 by Vickers-Armostrong, the 6 Tonner was the most influential tank design of the inter-war years, as well as nowadays. Although it was rejected to include in the armory, it made an impressive international career. Buyers included, but were not limited to, Bolivia, Bulgaria, Greece, Finland, Poland, Portugal, Republic of China, Siam (now Thailand) and Soviet Russia.
Comes with decals for 2 variations.
