I just won my first internet auction at the German egun, here is the result:

Merkel, Suhl, built 1966

a Bockbüchsflinte 7x57R and 12 gauge, 65 cm or 26'' barrels, with a quite modern Zeiss 2.5-10x52 scope in Suhl claw mounts (somewhat bulky but certainly useful for my hunting)

12 gauge shotgun barrels, choked half and full, 71 cm or 28'' long

best of all, a factory stock with length of pull 39 cm, around 15 1/4''
This is exactly what I need!
I couldn`t be more happy.
