What was the largest Rifled Gun mounted on a tank in WWII? I"m sure this will start a lively debate,remember the key word here is"rifled gun " not mortar.

Maybe polish light tanks TK/TKS with 20mm machine gun FK-A wzór (mark) 1938 - Szczeniak/Puppy. The Russian assembled 14,7mm antitank gun PTRS or PTRD . After the War, the some ammo 14,7mm was be using in KPWT/KPVT.
