312 GPO 'Call Exchange' Bakelite Telephone
We are now offering all our telephones with the option to purchase our own 'Dial-A-Tone' pulse to tone converter at a special 'bundle' price to ensure your telephone is compatible with BT 'Digital Voice' and other VOIP systems.
This is a lovely example of a British Bakelite 312 'Call Exchange'. The photographs are of the actual telephone for sale and accurately record its condition. The handset is marked 1956 (164 56).
This telephone is in first class working order and the case has a nice sheen. It also has a fully serviced No.12 dial with an alphanumeric 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.
Our full, top-quality restoration includes:
- Our own brand-new best quality cotton braided line and handset cords
- High quality correctly fitting replacement transmitter unit
- Fully serviced dial set with professional test equipment
- Quality replacement furniture
- Mechanically polished case
- Quality replacement feet
•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.
