Bought four guns from a "antique" dealer who had them shipped from GB without any import paperwork or duties in a sealed containers with house hold goods. Suspect he got cold feet. What I paid for them even the wife will never know. Sold two of them and paid off the last of her student loans she had before we married.
Saw one of the guns for sale before the 2008 crash for five times what I got for it. It sold quickly. Everyone had made money on that gun. I am sure the antique dealer made money on it, I did when I sold it to a dealer, he made money to the next buyer and then that seller made more money when he sold it. The only looser would be the last buyer if he paid top dollar just before the market crash. And even he will get his money back in the long run if he holds on to it long enough.
