The MG on the StuG II Ausf. G fired throuh the mantlet, and I have photos of vehicles with these fitted into the Saukopfblende (sow's head mantlet). Off-hand I cannot remember whether the modification was ever made on the composite mantlets made from flat plates. I'll check. It was Bob McNamara who spotted this feature from photos he had of StuG III Gs.
