An old farmer has a William & Powell 10 gauge hammergun sitting in his closet. His description is that "it has been hunted with, but very well cared for. Some engraving, Damascus barrels (32") and english style stock with a couple of dings". I am going to go see it this week (Monday or Tues.) and was wondering what sort of things to look for with these guns. I never get a chance to see many english guns and don't see much info out there about w&p hammer guns in general.

Asking price is $500. ($500 doesn't get you much these days so I want to be educated enough not to get myself hosed out of my money)
