This is a wonderful telephone and you can tell it was Swiss made as the dial turns like a Swiss made watch mechanism. The wall model of this telephone is now very sought after and not often seen but the desk set is even harder to find. I have never had another in ivory and bought this around 15 years ago I my collecting days. It is a little later than the Bakelite ones I have seen and dated 1973 and made from what epears to be an ABS material. This one has been stripped down and re built after each part has been cleaned and polished. I have fitted an electronic microphone and a quality grey plastic line in cord made by me. The telephone is fully working to both dial out and receive perfectly. I can make a dial label with your information at no extra charge. If you like it buy it as I don't think I have ever had another for sale on this site.
