Recommendations for Reference Book (Army Officials Insignia)?

[Litewka]

I am curious to know if any members could recommend a good reference book that includes a discussion about German Imperial Army insignia for administrative officials. Books in English and German are desirable. My sincerest thanks for any recommendations!

Litewka, which era are you interested in, pre-war or wartime?

Kind regards,

Wartime.

I would certainly recommend Jürgen Kraus' " Die feldgraue Uniformierung des deutschen Heeres 1907-1918". It exhaustively covers all branches of the military administration in its 2nd volume.
