There is one man in Canada Alex and hes asking about his o/u cape gun, who was Carl Grundig Royal Gunmaker (sign on barrels)?
I have to say I just once saw Grundig's gun and it was very nice gun. Also I know there is Grundig ammo.
Several photos of signs and proof marks on this gun.
Caliber 72/68 means plug diameter .400 or 10,16 mm and powder charge 39 G.B.P./St.m.G. Any bells what could it be?
Alex promised to send me photo of 1 cartrige and he is positive this is original one. But he'll send it in a week, hes out of home now.
If photos don't load, let me know, I'll move them to another place
