In regard to Jondar's comment:
Years ago, a gun dealer friend of mine came home from a gun show with "Johnny Ringo's" Winchester and Colt SAA, that he had bought for big money. For proof, the guns even came with a yellowed newspaper clipping telling how the Sheriff gathered them up. And don't you know?... that clipping even listed the serial numbers that matched the guns.
With a little checking, both guns were found to be manufactured years after Ringo died. Of course, the so-called newspaper clipping was a complete fake. A small section of an old Arizona paper was used, and the story of "Ringo's guns" was pasted in, a copy was made and then aged.
