On the scrounge yet again

. Having mislaid ( lost ) the armoured machine gun shield for my Stug III I am wondering if anyone has some ( side,top,front ) views of a very late Stug III with the remote operated machine gun,metal return rollers and pigshead style of mantlet as I am thinking of converting mine to the later type. Any help would be more than welcome. Also has anyone converted the early type mantlet to the later type pigshead mantlet. Once again any help in this department MORE than welcome as my scratch building skills are not the best. Many thanks in advance
