Special Exchange Fire Telephone No.81
£585.00 Coming Soon
This is a very rare example of a wall mounted No.81 Special Fire Telephone for use in telephone exchanges. It is an elaborate hardwood box with a hand cranked generator locked off with a pinned arm. Above this is mounted a standard 232 combined set.
This is a genuinely a magnificent piece of telecommunications history. The original parts are present and it is a truly elaborate construction. It has been carefully restored and is really a special piece.
The combined set has been wired as a standard 232 and will ring and take incoming calls. There was no dial facility on a No.81, which originally used the hand cranked generator to make the call connection.
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 Bakelite case
•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.
•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 as required.
