The reason behind my question is, that I own two books. Both show the same picture, but one book says it is Hauptmann Adolf Koch, the other says it shows Lieutenant Theunissen. Who is right, wo is wrong?
Hopefull I don't do copyright violation. See picture below. Source: German Military Cuffbands 1784-Present, by G. Williamson & T. McGuirl, R. James Bender Publishing, ISBN 0-912138-74-2, 1st Edition.
Btw: maybe I mixed up Theunissen with Larsen? What did you write in your book mz?
