World of Lugers Proof Marks

Bear in mind that a lot of the info contained within that book is rubbish. That was established many years ago on Auto-Mag. Remember; the people who put this book together are the same ones who brought you the infamous "SD" Luger, 12 - 15 years ago. The actual intent of the book appeared to be; to lend validty to faked items. There is some "good" info in the book, but you need to know enough to sort the fly-poop from the pepper.
