A friend (yes I have one or two
) looked at a Parker Lifter serial number 12656 with Wells Fargo stampings. The gun is a 10ga w/20 inch bbls. I would assume that Parker as well as other companies provided guns to various companies. This gun isn't in the serialization book and the owner is curious as to it's authenticity. Would a research letter shed any additional information if it's not in the book?
