Wehrmacht Extension Cable for the FF33 Field Telephone (Verlängerungskabel zum Hörer für Feldfernsprecher FF33) or for the 'Flaksprechgarnitur'. Accurate intelligence and secure lines of communication are crucial elements to all armies in the field and during WWII each division in the German Army had an integral Signals unit. The Feldfernsprecher 33 was the standard issue field telephone used by the German military during WWII. This is an extension cable which could be used for the phone of the FF33 field telephone set. It is nicely maker marked and dated 1942/1943, the cable is in very good condition. Nice piece of equipment!
