GERMAN TELEPHONE EXCHANGE 10 LINE

Known as a Small Flap Cabinet, or Klappenschrank in German (Clapboard). Switching is achieved by loose cords and plugs, with flaps on the front to indicate that a phone has been lifted, buttons on the front can select one circuit at a time presumably for the operators headset. Dated 1940.
Inside is the manufacturers logo, which is a gear wheel or sun, with no identifiable marking inside the circle, and has been marked by us as Unknown Manufacture. Two more of these units have been found, one made in German occupied Czechoslovakia by Prchal- Ericsson, and the other by Franz Lange, Precision Mechanics and Electrical Works Berlin. As per our comment another is in America made by Prchal- Ericsson.

Your comments:

• A large number of these switchboards where by all service branches of the German occupation forces, and seems to be quite common here.
  Handling a lot of them through the years, I have never found any plates or otherwise stamped manufactures documentation in any of them, only year-stamps and WaA-205 stamps
