Wehrmacht Morse Code Telegraph Key (Telegrafschlüssel). The Morse code telegraph key could be used in conjunction with most German field radios. This is the model 'Baumuster: T1', the device is nicely marked with 'Anf.Z.:Ln26902'. The morse code telegraph key is complete with its original anti-slip rubber base. The set is in good used condition. Very nice and quite scarce piece of equipment!
