Telephone No4.

This is a early No4 Candlestick phone and was used from 1906 onwards. The phone would be connected to a bell set No5 to complete the set. This would contain capacitor, induction coil and bell for the unit to work correctly. The transmitter rotates round to agetate the carbon granules in the transmitter (No3) to gain clear audio output. |
Tele No2/150
|
This is a GPO manual exchange No2 Telephone which was introduced in 1906. This one was converted by the GPO circa 1924 into a tele 150. This can be seen on the top of the stem where the No2 is crossed out and replaced with a 150. As a manual exchange telephone it has no dial, instead it is fitted with a blanking plate. This could then be removed at a later date and replaced with a dial when the exchange went automatic. This phone would be connected to a bell set No1, this would contail the coil, cap and bell's for the phone. . |
