Hello Dwight,
I have found the forum some days ago and it's interesting to read through all the postings. Nice Lugers here
Too bad that I can't collect them, because my license is for rifles only.
Well, I have only included the code-markings (numbers and letters) of manufacturers and two tables with the codes for the year of production.
The only Zeug�¤mter that are included are the following, because they have had an official code:
136 Heeres-Zeugamt Kassel
137 Heeres-Zeugamt K�¶nigsberg
977 Kraftfahr- und Radfahr-Zeugamt "Kurza" Wien
czo Heeres-Zeugamt K�¶nigsberg
jlj Heeres-Zeugamt Ingolstadt
Please see attached another picture.
I have startet doing that work just for my own many years ago ... stupid work to check and correct 9200 lines of codes and addresses

But I'm happy about the result, because I have never thought that I could find a publisher. 500 pages is a thick pack of paper.
With best wishes
Michael
