K 190

RAILWAY TELEPHONE
AS USED ON ALL THE PRINCIPAL RAILWAYS IN GREAT BRITAIN

Long Distance
Railway Telephone for Signal Cabins

Specially constructed with Relay for Long Line or Bridge Signalling. With one  Receiver, Lightning Arrestors and Microphone fitted behind a flat diaphragm.  The fear of contagion through several persons using the same telephone is thus minimised.

Similar to K192 but only has one receiver.
