In your first post, you say that Gary has the gun. Is he refusing to refund your money? Is he refusing to send the gun back to you at his expense? How does he propose to "work something out"? If you put up a fight, his legal expenses will exceed the value of the gun. So will yours. The problem I see is that his original ad doesn't say anything about "original finish". How would your lawyer see that aspect? Did the dealers who valued the gun at $10,000.00 value the gun as original or refinished?
