This has been fitted with a pulse to tone unit and so will work perfectly with any telephone provider.
This is as nice an example as you will find. Wall telephones are far less common the desk examples and so I rarely get them as good as this one. This has been totally stripped down and re built after each part has been inspected cleaned and polished. I have fitted it with an electronic microphone, a very best quality hand plaited braided handset cord and a D shaped quality line in cord made by me. This has been fully tested and set up to work perfectly. I has a genuine GPO chrome No12 dial with an alpha numeric dial face. I can make a dial label with your information at no extra charge.
