As we have found over the years, Daryl is right on. I will never say never as long as my friend Doctor McPhail can provide an example of a strange phenomenon in gunmaking. If Clark and Sneider built a ten gauge with 12 gauge bores, Tom Golcher probably put a few together to compete. After all, they were after the same market along the Delaware River and down to the Maryland Shore. We Maryland boys were (and are) dumb as stones and would buy anything that would shoot big bullets and is hard to carry.
