thats looking realy different
the parts you looking for can be made, no doubt. but without the original parts in the hand for taking measurments and study it inside it will be only close to the original. if this is the right thing for you? must have been a gunmaker special from Suihl/Zella Mehlis before the first war.
do you think the claw mount was made post WW 2 because the orignal scope was lost? anyway, its a nice chance to fit two different scopes to this rifle.

would be nice if you could make more pics
