TELEPHONE No. 10 | |||||||||||||||
CB Pedestal telephone This is a C.B. Candlestick style, table telephone with a press button fitted in the base. The press button would be used to ring a trembler bell at an extension. The telephone was originally called the "Telephone, Table, C.B., with Press Button, Transmitter Type". The press button and cable entry grommet were made of ebonite. The telephone required a Bellset as there was no Induction Coil or Bell Ringer in the casing. This telephone can be have an additional receiver hook fitted. This was ordered separately and the Mark 235 used a "Hook, Receiver D". There was a Mark 234 and a Mark 235. The Mark 234 was the golf ball type (pictured to the right) whilst the Mark 235 was base on the standard GPO style candlestick - Telephone No. 2. This was the table equivalent of the wall mounted Telephone No. 7. Early table telephones were connected to the internal wiring with a Strip, Flexible Cord Connection.

The picture above shows an earlier variant, later variants (Mark 235) looked like the standard British candlestick (see picture below). These early models were made by the Western Electric Co. probably at their BTMC factory. The press button was used to call a buzzer on another phone to advise there was a call for them. The switch hook contact springs consisted of three contacts that made contact with each other on operation. The early type used a Transmitter No. 1 which could have Label No. 43 fitted between the speaking tube and the transmitter body. This label advised of the Exchange name and number. See picture below.
