You guys want pictures of everything people see, but you have to remember you can't take always cameras into the gun shows (I)you go to. I can only tell what I have seen or have written down. But finding unusual stampings (or no stampings where they are supposed to be) on Winchesters will never surprise me or be that unusual. At least it won't make it that more valuable than an average one. Plus I have learned whenever you ask someone who is supposed to be knowledgeable, he will usually have a different story than the next guy who is supposed to be knowledgeable on the subject. Good luck.
