Field Telephones of WW I
Waetzman" consisted of a sensitive microphone welded to a rouund shaped platform and of the handset that we have on display. All the parts were
delivered in a wooden crate which in fact was a cabinet of "Iron" Army
Field Telephone (Eiserner Armeefernsprecher) which became obsolete after FF-16
field telephones arrived.
"Horchgerät Waetzman" was used to detect underground
enemy activities of digging tunnels for explosives. Such activities
have been quite common at certain periods of WW I when both
counterparts had no chance for attacks because the defence lines
were too strong.
