FF33 Kopffernhörer 33 strap marked S.A.W. München 1937

Very nice original spare headphone strap or Kopffernhörer fuhr den Feldfernsprecher 33. Couples to the Kopffernhörer right into the FF33 and enables a second man to listen to the conversations on the line. Nicely marked S.A.W. München 1937. Excellent example!
