Comparing: Vickers Mk. E Type B vs. T1E6

Developed in 1928 by J. V. Carden and V. Loyd. The vehicle never entered service in Great Britain. However, it was exported to other countries, including China. In 1937, twenty vehicles of this type fought against Japanese troops at Shanghai. Soviet Vickers-based T-26 vehicles were also exported to China, and 82 vehicles of that type were deployed in South China and Birma in 1941–1942.

Experimental vehicles T1E4 through T1E6 were heavily influenced by the British Vickers E. The first prototype was manufactured by the Cunningham corporation in 1931. After trials in 1932, an upgraded variant was built. However, a different experimental tank, the T2, was preferred.
