K 215


Pocket Type
Colliery Tapping Telephone

With “Ringing” and “Speaking” Keys. The Wires are run bare, and the Expanding Arms of the Telephone are intended to hook one on to each line, so establishing connection with the Engine House.

The “Ring” Receiver shown is used both as Receiver and Transmitter, and although not so efficient as a Microphone,  still gives good results, and possesses the advantage of portability.

Cost in 1904 - £1.10.0
