They seem to have made these in assortment of types. Mine is a 12ga 30" weighing about 7½ lbs, choked full in both bbls. Most likely built as a waterfowl gun. Has a semi-pistol grip (POW) & a leather covered cheek piece. The leather has been torn & underneath is what appears to be cork which is inlet into the stock, not just set on top of it. I would not count on the lighter weight "Game Guns" having the 70mm chambers. Mine does not carry nitro proof marks, but this is the norm on pre 1912 guns due to Germany's rules of the era.
