This shotgun was in my parents attic since at least 1950. According to the reseach on the internet it was manufactured in 1894. I checked the chamber with a primitive device and it is approximately 3". Can you tell me if that is the original chamber debth, or was it reworked. Also,
if I want or need more information, should I buy a book referring to L.C.Smith.Any guestions back to me, please ask.
