TELEPHONE No. 396

Combined, Bakelite cased, table telephone used by the BPO in CBS No's 1, 2, 3 & Magneto exchange areas on private circuits without transmission feeds and in mobile vans.

Fitted with a dummy dial, the telephone has no provision for press buttons, but the chassis may be found in a three button case as some were used during WW2 and modified for secrecy working.

This telephone had a tray for the subscribers personal directory but as from June 1940 the tray was not fitted and instead the telephone was supplied with a Tray, Dummy, D62099 (a blank plate). This was probably a war time cost saving, as in late 1947 the tray was re-introduced.

An alternative to the Telephone No. 1/196LB with Bellset No. 31.

This was a Local Battery telephone and therefore requires batteries to power the transmitter.

Available in the colours - Jade green, Chinese red, Black and Ivory.

This phone shown in the picture would have been connected to a scrambler unit and the handset has been changed to a green variant to identify that the phone could be switched to scramble the speech.

Mark 1 - has a Receiver, Inset No. 1L in the handset and switch bracket with plungers of the early type.
Mark 1A - has a Receiver, Inset No. 1L in the handset and switch bracket with plungers of an improved type.
Mark 2 - has a Receiver, Inset No. 2P in the handset and switch bracket with plungers of the early type.
