TELEPHONE No. 396 | |||||||
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. Available in the colours - Jade green, Chinese red, Black and Ivory. This phone 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 make speech secret. Supplied to the BPO by Ericsson, their Model N8440. Pictures courtesy of Ian Nichol. Circuit diagram - N496. Diagram for the Button labels - N620.
