Description
The Army field telephones originated in 1899 when the first communications units (Telegrafen-Bataillons) of German Imperial Army were raised. The first model of the Army field telephone was of Siemens design of 1894 and was called “Patrouillenapparat”.
Next the 1905 model has arrived which was in use all thru WW I despite the newer model of 1913, Eiserner Armeefernsprecher or “Iron Army field telephone”, has come into production. On top of push-to-talk key, “Armeefernsprechgerät alter Art” had two round shaped keys, one at each side of the telephone body. White key on the right side was Calling Button (Summerknopf) while black key on the left side allowed to increase temporarily, the strength of incoming signals.
