Any of you know someone who is looking to buy one of these? I have 2 that are back-to-back serial numbered. Open sights. Not real sure what they are worth, but I found them on line new for $400 each a while back. Probably looking to sell for $500 as a pair, or $300 each if bust pair. Any thoughts? I don't even know where to sell them here as Texas is not much of a Muzzle Loader state.
