Hello Bob, thank you for your kind comment. I am in the process of finishing my publication on Oflag VII A. I have researched the topic for a number of years. I do have several sources, which I don't like to reveal at this point, but will gladly do so after the release of the book. I am very sorry that my answer is a little disappointing for now.
Hauptmann Oswald Pohl's Soldbuch, Wehrpass & Sonderausweis can be seen here. He also has the Soldbuch grouping of the camp's translator:

Than you, hucks, I saw that. Amazing!
