Comparing: BDR G1 B vs. Churchill I

The project of a new vehicle was suggested by engineers of the Baudet-Donon-Rousell company in June 1938. However, the design was never developed.

The A22 prototype was built by Vauxhall Motors in the fall of 1940. The vehicle first entered mass production in the summer of 1941. Early modifications had no track fenders, a different fan, and a 3-inch howitzer in the hull. A total of 300 Churchill I tanks were manufactured.
