I gues that not that easy .Most of the turrets got no cupola mostly they are welded to give agressors no chance to get acecss to the turret from outside …I never saw such a flap as well behind the turret to get inside there are Panzertüren from the rear .

There was only one Bunker with Panzer III turret ever build on Kummersdorf proving Ground .Maybe in the later time of the war The light gun was outdated against all allied Tanks and the HE was not so effective
