docbill - suggest you do a search for the A.H. Fox Collectors Association website and check out the excellent information on grades, mechanisms, and other basic identification information. A.H. Fox guns are classic workhorses but many have been abused over their long lives as there are also lots of good ones for reasonable prices out there. I suggest getting to know much more about this great American double gun maker before you decide on the first one you come across.

All the best,
