I'm guessing this is a Model 1766. It has "Charleville" stamped in script on the lock, and on the opposite side of the stock, carved into the wood, figures which look like 1 x F. On that same side there is a ball strike (someone apparently shot at the owner and hit the stock -- perhaps a pistol?). My dad had a sporting goods store when he got back from WWII (Vermont) and took in any number of weapons as trade for fishing tackle, etc. This Musket was one. Action no longer works but appears to be original. Any info would be appreciated. Thanks!
