Ffh 39d (Festungsfernhörer 39 doppelt) Bunker Headset

Searching  for this headset for couple of years, finally got this set but the last owner had modified it from five pins phone plug to audio two prong plug and still functioning.

How lackey I were.

Put on a pair of orange brown rubber pads to distinguish it from the Panzer headsets I own.

It has only two parts extra metal parts from standard Panzer headset Dfh.b.

And two leather loops to secure the cable on the leather sleeve.
