Thanks Everyone for your help. Ellenbr, I am positive it says C. Adam Coln A/Rh. I am assuming C. Adam is a retailer like others have pointed out and he lived near the Rhine River in Cologne Germany (Thanks Der Ami). I couldn't find any information either on this person other than what is spelled on top of the barrels in the rib (Silver Inlaid).
I did some more measuring with my calipers and am almost positive it is a 9.3 x 62R (all dimensions fit, using my reloading calibers manual). The muzzle of the barrel actually measures .365" or 9.3mm. I am not sure what the "9" and the "X 47" marked on the bottom of the barrels means then though?? (does anyone?)
I haven't found much information on Mr. Luck that made the gun??
Thanks Everyone!
