Damn, i have seen a picture of a scope on a MG42. And not one of those range finders, a sniper-rifles scope. Ill see if i can dig it up for you guys.
Edit:
Double Damn, i was wrong. It was those telescopic/ranger finder sights. I should learn not to object the facts told on this forum.
*Click it*
Heres the pic, thought you guys might get a kick out of it anyway.
It is from the Eastern Front.
P.S That is a great set of photos from the eastern front, check the album.
