GERMAN TELEPHONE EXCHANGE SIEMENS

Believed to have been made by Siemens in Germany during WW2 but there is no military markings on the unit. 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

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

• It is made by prchal-ericsson. 1943. I have the identical one in pristine condition. Yours is the only other I have seen.
