Sometimes it is as simple as people know one dealer always has a good number of high condition guns and when they decide to sell that is the dealer they use. Then there was a dealer many years ago who bought a 20 ga. fox graded gun from me which was in decent but not pristine shape by any means. About a year later it appeared on his web site for sale as a pristine, high condition, factory original gun. I called about it and asked him if he wanted any before pictures sinde he only seemed to have after pictures. He hung up. So buy with a little bit of doubt until proven otherwise.
