That looks like a corker of an old gun...in awesome condition, hardly used....If your up for shooting Damascus...& have it looked at by a good Smith that knows his stuff...why hang it on wall?
with nice mild 7/8 or 1oz loads why wouldn't she be good for a nother good few years.
I think it's grand,..... beautiful actually
good luck with it man
