I saw a longrifle in a curio shop in Arkansas over the weekend that looked all original except for a replaced lock bolt, and had a modest price tag, but I neither bought it nor photo'd it, unfortunately....It had a Leman percussion lock on it and what looked like a hammer forged barrel of about .36 +/-. The furniture was brass and it had a 'fish belly' butt stock of what looked like dark-stained maple. Does that tell anyone enough to place it regionally? I may have to go back and look at it again...I don't remember seeing any makers mark on the barrel. The price was appealing, but I was shopping for an anniversary gift for my wife!
