I just went to a small antique gunshow last week, it's was sponsored by our state gun collector's guild. There were about 40-50 small tables, everybody has a niche or specialty. There are many different kinds and styles of guns in every state of condition, so the prices vary widely.
Some gunshops carry antiques also, but certainly not as wide of a selection and the prices aren't always as flexible.
You need to know what you want, and a person would have to inspect the piece very thoroughly to determine the condition.
Civil War era guns seem to be much more expensive nowdays.
Sometimes when I go to shows, I get obtain contact information so that I can contact the person after the show is over to make a deal for a gun. No one likes to make a bad decision by buying a gun on the spot without further considering other guns at the show, or to contemplate the purchase.
So, sometimes I make contacts with the area antique gun dealers that way. Pretty much the same people are usually found selling their wares at the shows anyways. And they are held periodically, depending on the organization, 1 - 3 times a year.
