The "hogback" stock is very distinctive of Bavarian rifles, not European rifles in general. The design aligns the shooter's eye with the sights very handily. Before scopes became popular for American shooters, American stocks had that much drop at the heel too, only without the raised comb. From the 1950s on, Americans switched to what we call "Classic" stocks with less drop at the heel to help with recoil management and using scopes, while our European counterparts continued to use a more traditional stock since magnums were not as common "over there".
