Conley,
that depends, who is the name on the "papers", and the date. I've seen papers that were supposedly "authentic", when they were in fact recently signed and "backdated" by former employees. One such item I've seen floating around here in WA, and was posted on Gunsamerica by someone I've dealt with before. The owner of this "unique" item paid a former "famous" employee to authenticate his item. Be careful.
