The Amtszusatz was a rotary dial attachment for the small, 10-line field telephone switchboard. It enabled the switchboard operator to make and receive telephone calls via the long distance telephone network. To find out more about the Amtszusatz, check out my new book on World War 2 German field telephone equipment. The book is chocked full of photos, plans, drawings, and diagrams. It also contains information about male and female uniforms, speaking protocols, and forms. The 224-page book is available for only $44.99US (plus shipping) though the Lulu website at:
