This is a Falling Block Rifle made by Oscar Will of Zella St. Blasii near Suhl in 1924, the original caliber was 8.15x46R. The barrel is sleeved to 6.5x57r. It has an octagon barrel with original iron sights. Weight 2.5 kg without scope. I know this is far from original, but still a very nice rifle for shooting and hunting!
