It's a neat early piece but would take a lot to restore it. It started out as a snaphaunce and was converted to flintlock. Good for display right now. I'd like $75 for it. Originally sold for 50GBP years ago. I've made no attempt to clean it off. Plus shipping from 24426. I accept PayPal (you pay any fees), cash app, Venmo, Zelle, check or money order.
