"I mean if one of us or a friend were selling...we could help you out.". My father and I haven't been to a gun show in a few years. The last time we went, there were a few private sellers who had tables and were selling small, private collections. Perhaps, this isn't done anymore(?). If it is still allowed (private sellers with tables, then yes, I am seeking recommendations on who they are and what table they would be at.
"Your question comes off as if there is a specific reason you need to find a "private" seller." Buyer's preference. My father just enjoys buying from a hobbyist or enthusiast.
"The Odd part : If the reason is that the buyer (your father) is unable to purchase from a dealer due to legal issues, then personaly I would hope that all sellers follow the law , including the private sellers." My father and I are legal, not in trouble, law abiding citizens and are able to make purchases Personally, we hope the sellers follow the law, too, hence the request for recommendations...
My goodness, some minds are getting carried away here, but I understand and appreciate the hyper vigilance.
