Anyone have or ever seen one of these before? I got two of them in a box of "junk" that I bought at a recent auction. They are large hardback books with a dust jacket. One is in very good condition and the other in fair. They are older books, but show exploded parts diagrams of various types of firearms. They contain a lot of info about each weapon also. I thought they were pretty cool and was surprised that I had not seen them before.
