Joe,
I mean something done by the owner, not the maker. Usually something that is simple and often no particularly traditional.
I think it is one of those things that you know it when you see it. And usually, you don't see it.
Take the 10 pt buck that some kid carves in his bolt action shotgun here in Iowa. Hideous. It is an attempt to make something that looks sort of professional and fails by miles.
Ever watch The Antique Road Show? It occasionally has a nice piece of folk art carving on a piece of furniture or, rarely, a firearm. Some of these can be quite valuable.
Like I said, I need to find some examples and I don't have any.
Michael. That's a nice horn. The moose is just in the gangly stage. He will grow out of it
