German Kriegsmarine instruction manual “Funkgeratekunde“

Very rare kriegsmarine instruction manual about radio devices on different types of vessels. Also schemes of U boat communication appliances are  in this manual. A lot of fold out pages not all are photographed. Nice details is the stamp inside stating Nederlandse Militaire missie bij de geallieerde controle commissie technische afdeling. For the rest the manual is nicely stamped and numbered. Dated 1937. Great manual for the Kriegsmarine and WW2 radio collector.
