Dear All,

I believe the book in question is:

Deutsche Fertigungskennzeichen bis 1945 (German secret armament codes until 1945), by Michael Heidler, Visier-Edition, Das International Waffen-Magazin, Stand Feruar 2008. I paid $63.00 USD via PayPal, which included shipping to the U.S. I interacted directly with the author.

Hope this helps.

Regards,
Richard
