This was used quite early in the FuG III, FuG V, and FuG VII (with Adb 6 connection). This plug was located as part of the pilot's flight helmet. The pilot would plug the wire from the radio directly into this plug on his helmet for easy communication with other pilots. This is the connection that plugged TO the German Flight Helmet LpKN101, LpKW101, etc.
Made of bakelite and aluminum, this helmet plug and wire extension is in SUPERB used condition. It has some very minor scratches due to the age, but nothing that take away from the overall appearance. Number is easy to read on each plug, and the wiring is 100% intact, however it is a bit dirty.
A PERFECT addition to any collection, display, or restoration project!
