Hold on, fellas, wanna give my .2C on the original subject before the thread gets too hijacked.
60mm armour, modeled correctly in AH, would only stop maybe the 37mm and T-34's short 76mm rounds. And it would be iffy on the 76. On the other hand, The italian gun would be probably a little weaker, if not the same, as the T-34's. The HP/ton isn't on par with the T-34, this thing would be somewhere between the Pz. IV, and the Tiger. In short, It would be in danger of becoming a hangar queen. If any italian tanks were modeled, though, this would probably be the best foot forward.
