Comparing: T56 GMC vs. Valentine AT

A109_T56_GMC

Development of a 3 inch self-propelled gun on the M3A3 Stuart chassis started in September 1942. Trials on the Aberdeen Proving Ground in November demonstrated that the gun was too heavy for the light tank chassis. Never entered mass production.

GB42_Valentine_AT

This experimental tank destroyer had the gun mounted in the middle of the hull behind a gun shield. A prototype was built, but work on the vehicle was discontinued when a new tank destroyer was developed, based on the Valentine and mounting the powerful 17-pounder.
