You haven't shot any turkeys lately, have you, jOe? I sympathise: I know the crabby feeling one gets from being skunked - the Red Gods have been frowning at me and handing me the horse collar lately. I'm trying to figure out what I've done that's irritated them, so I can get back on their good side before the seasons close around here.
Back On-topic.
When I posted my prior comment on the thread, about getting the gun checked out, etc., I was operating under the belief the owner wanted it for a shooter. If it's exclusively as a wall-hanger, a little work on the stock and a good cleaning will probably be enough. Hang it so the non-matching hammer is against the wall and that will be that.
