Re: C.S. Shattuck Shotgun???
I too have a C.S. Shattuck single shot 12 ga. shotgun I inherited from my father just like the one depicted in the picture. Serial #38059. My dad used to hunt with it when he was a teenager back in the 40's. It was my grandfather's gun originally.
Dad told stories of a raw trigger finger from it slapping against the backside of the ring trigger every time he fired the gun and several pheasant that got away when he pulled the ring instead of the trigger to fire the gun.
