Congrats!
I used to buy at gun shows all the time. Lots of antiques. Many old couples selling together. One time, after rules were tightened, I watched a very old lady argue with a large Marshall over receipts. He wanted proof that she had a legal right to sell jewelry she had purchased back in the forties and her mother had purchased before WWI. Ha.
She managed to straighten him out somehow as I bought to my heart's content.
