The T-26 light tank design is derived from the British Vickers 6-ton tank. In early 1930s, a Soviet buying committee traveled to Britain and purchased tanks, tractors, and cars for use in the Soviet Union, of which the Vickers tank was chosen. Fifteen Twin-turreted Vickers tank arrived into the Soviet Union in May 1930, equipped with only machine guns. Four more Vickers were delivered at the end of 1930, these being the single-turret variants with a 47 mm gun, and the deliveries were finished by 1932. The Vickers-produced tanks were designated as the V-26.
