Comparing: Excelsior vs. Matilda Black Prince

At the end of 1942, the Churchill tank's armament was deemed insufficient. New tanks, the A31, A32, and A33 were developed as new infantry tanks. The A33 was developed by the English Electric Company. The LMS Company participated in the development of suspension for a new tank. Two vehicles, which differed greatly from each other, were manufactured. The A33 was set to go into production, but in 1943 the decision to cancel mass production of the Churchill was reversed, and the order for the A33 was not placed.

This vehicle features a 6-pounder gun fitted in the A27 turret. Only one prototype was produced, after which development was discontinued due to complications with the turret mounting. The vehicle never entered service.
