About the telephone
This is an exceptional example of a British Bakelite 328 first introduced by the GPO in 1937. It has the very useful feature of having latching buttons to allow the bell to be turned on and off. This example has a handset dated 1955 (164 55). It in first class working order and the case has a nice sheen. It has a fully serviced No.12 dial with a rarer enamel numeric dial plate. All cords have been replaced with my own, UK manufactured, pure Egyptian cotton braided cords correctly terminated with cotton ties.
The telephone comes complete with our own high quality reproduction paper furniture. The dial label can be customised with an area and telephone number of your choice.

Restoration Details:
•Handsets and cases are stripped of their components and thoroughly cleaned.
•Cases are polished, both mechanically and by hand. It has taken me many years to perfect this technique and it will return the case to the best possible condition. Polishing by hand alone will not achieve the best results.
•All contacts are cleaned, set and polished.
•Dials are stripped, cleaned, inspected, lubricated and rebuilt. This includes the removal and cleaning of the governor, governor cup and main bearing. The contacts are set and the dial speed and MK /BK ratio set. This is an essential part of making a telephone work properly.
•Bell coils are set and any necessary adjustment made so their resistance is suitable for modern networks.
•A new line cord is fitted and the telephone is reassembled with the appropriate wiring alterations made to allow it to function on a pulse dialling system.
•Mouthpiece are fitted with a modern electronic transmitter to provide high quality speech.
•Finally, telephones are tested on a live line to ensure they are working correctly and a custom dial label is fitted.
