The Valentine I, Infantry Tank Mk III, was the only version of the Valentine tank to use a petrol engine, and was armed with the standard 2-pounder gun of early war British tanks.
The Valentine I was powered by a 135hp A.E.C. 6-cylinder gasoline engine, as also used in the A10 heavy cruiser tank. It had a two man turret and was armed with the 2-pounder anti-tank gun and a coaxial 7.92mm Besa machine gun. In the two man turret the commander also acted as the loader.
The Mk I was produced in 1940 and a total of 350 were built. It didn't officially gain the Valentine I designation until June 1941.
