Italeri has been notorious for fit problems ,but keep this in mind , the rear armor turret plate is overlapped, slightly , by the side plates on panther turrets ,tamiya and dragon also do this , so I would imagine the real one does too . Zimmerit was pretty much standard on all tanks until very late in the war when germany was crumbling , However scale wise the zimmerit is very thin (less than a millimeter ) and will not cover up severe fit flaws , just slight cracks . So anyways ..... very late A tanks and Late G tanks no zimmerit , before that they had it .
