My wife's father left her a couple of rifles. One was a Remington .22 pump takedown in .22WRF. Anyway the other she said was a shotgun. I don't care for shot guns so I never really looked at it till yesterday. Its a drilling. It appears to be German made , there are no makers logo anywhere. It is a bottom lock ,bottom lever. 16ga side by side with a 9.7 X 72 on the bottom. There are 3 boxes of ammo in the case they are 9.3 X 72R . In really great shape. The ammo is badly corroded. Anyway here are the markings on the barrels, both barrels are marked the same. Shotgun- German Eagle (GE from now on) Nitro. Crown S , Crown W, Crown U, (2) GE and the number 16 The rifle barrel Krupp-Essen, Crown G, Crown N, Crown E , Crown U , and Stm. G over 13gr. 9.7 over 72 and the date 9/26 With this info can anyone tell me who made it , the correct caliber, and what does all that mean? Thanks guys.
