Unissued Dfh.f headphones dated 1940

Excellent headphones for usage with the field radios or dfh.f (Doppelfernhörer für Feldfunkgeräte). The headphones are in unissued condition and complete with the original cord, plug and the Erzatsmaterial band. The headphones are nicely dated 1940. Excellent example which would look great for a radio operators display!
