Incidentally, the Centurion mk. 1 is what World of Tanks players ASSUME St. Gloriana has waiting in their garages. Ironically, the Cromwell used by Earl Grey wasn't included here.
The Centurion depicted is the Mk 3 with the welded turret. The original Centurion has a cast turret, an independent loader-operated ball mount 20mm Polsten and no stowage racks.
