Here's an old one. I'd actually appreciate any info anyone can give me on this. I recently bought this from a gent in West Virginia. I was told it is a English 9mm pinfire, from the 1850's or 60's most likely. The small dots on it are supposedly sterling silver , and I believe the brass colored inlay is in fact brass. I was told it was gold, but I doubt that. It is in working order but it looks to me as if it has had a bit of repair work. A crown over the letter G is the only proof mark I can find that is located on the cylinder, and Google has not helped me much determining what that means as far as a manufacturer goes.
