Did the Cromwell have the MK 5 6 pounder or the MK 3 6 pounder, because it would seam from the reference below that the later could not fire the APDS rounds, that were so effective against the Later War German tanks ?


While your reference doesn't show any reference to the APDs round in the table for ammo for the Mark 3, l know of no reason why it couldn't fire the round, as only the barrel was shorter.
