Buy it as a wall hanger. Much less chance to be disappointed later. Much better to buy it cheap and find out that it is a decent gun worth more than pay top dollar and be stuck with a piece of junk worth a hundred that you paid a thousand dollars for.

Condition is every thing. If it is pitted, worn or in rough shape it is just a wall hanger no matter what you pay for it. Not easy to check proof marks if they will not let you remover the barrels from the stock. Look at the bores as best you can. Heavy pitting should make you know that it is a wall hanger. Not a sin to own a old wall hanger and they are a real lot of fun to have in a gun room. Just do not try to shoot a 150 year old wall hanger. Two eyes, eight finger, two thumbs, two hands and two arms are not to be risked on a whim with some old wall hanger. There are thousands of reproductions that are safe to shoot instead of one old wall hanger.
