World of Lugers Proof Marks

I would love to answer all of your questions but would do so only off line, I have a feeling that you may know as much or more about the answers than I do anyway. As far as the book itself goes, I think it is overall extremely good and in many ways a milestone in collectable firearms reference formats. There are some errors I know for sure and probably some that I have'nt even caught. Many of the exoctic markings like the Afrika Korps palm tree is noted as being mostly fake (I would say ALL fake) other things are just a result of weak research like the BAXXI (or whatever numeral) meaning 21st Battlion rather than Bekliedungs Amt 21st Armee Korp, which all of us Imperial militaria collectors knew well 25 years ago when the book came out. I for one really like the systematic way Costanzo covers the marking combinations and the excellent approach to cross referencing the material throughout the book.
