I like it. I agree with Dan, not a G&H, possibly a Stoeger, or one of many unknown gunsmiths, either professional or above average hobbyist, who possible ordered his parts from Stoeger. More surprising to me than the bore is the fact that it made it through all these years without anyone drilling any extra holes in the receiver or barrel. That is nearly impossible to find. Nice find, hope you enjoy it. I suspect if you shoot it you will be impressed with how it shoots.
