A very rare electric signaling disc of the Feldgendarmerie. The handle and the disc are made from wood. In the center of the disc are the signal lamps. Marked "WaA" and dated "1940". No damage to the glass.
There is a metal plate on the handle with the manufacturer's address. On the back of the handle is the button to turn the signal lamps on and off. The handle can be opened at the bottom to insert the batteries.
