Peripherals for the radio: Headphone Dfh.a

The resin panel is nowhere to find, but the peripherals for the radio are also a must for the set. 
So I hunt for the headsets first, found this one in fair price and acceptable condition, only needs cleaning and fix the wire.

Markings: Dfh.a  41

Its a text book sample; 
Wehrmacht 'Dfh.a' Headphone (Doppelfernhörer). 
Marked with "Dfh.a" indicating 'Doppelferhöner' model 'a'.
This headphone is the standard type Wehrmacht headphone used with most radio types.
