Possible british mid-tier premium medium? Cavalier

Lert: A design step between the Crusader and the Cromwell, several prototypes of A24 Cavalier were built but none used in action as a gun tank. Several were modified and used as artillery command vehicle and recovery vehicles though.     Some vitals:   Full name: Tank, Cruiser, Mk VII Cavalier (A24) Weight: 27 tons Engine: 410 hp Nuffield Liberty petrol Crew: 5 (TC, driver, radioman, gunner, loader) Speed: 39 kph Armament: QF 6pdr 57mm gun Armor: 70mm max   Wiki page   This tank is historically moderately significant as it was one of the competing prototypes for what would become the Cromwell, and was actually built in steel in several numbers. I believe this tank would fit very well at tier 5 or tier 6 as premium medium tank, as it would be very similar to a slightly undergunned M4A2E8, or similar to a half upgraded in-game Cromwell.
