New book about German military codes of manufacturers

[GGG]

Hello everybody,
I just want to inform you that my book about the secret German manufacturer codes is sold out now.

But I was able to obtain a few books again. Price is 70 USD inclusive shipping by airmail.
But that's all. No idea if there will ever be a reprint in the future.

I have attached a file with corrections and supplements for all owners of my book. The list contains information that I got after the book was finished.

Viele Grüße
With best wishes

Michael Heidler
