As you can see this is a wonderful telephone made by GEC. This is a very solid and beautiful design and has two bells of different tones inside giving a lovely ring. It has been totally stripped down and rebuilt after each part has been cleaned and polished. It has a double gong mechanical ringer producing a lovely ring tone. It can be dated form the internal ring capacitor dated 1940 and so this was in use through world war 2. The dial is a GPO No 10 with enamel figure only dial face with some staining but totally original. This is a wonderful telephone and has been fitted with an electronic microphone and a very best quality brown hand plaited all British manufactured braided handset cord and a quality D shaped plastic line in cord made by me. Note the solid brass base plate. It is fully converted and set up to work using a special line simulator and then tested on my own BT line to ensure it is working perfectly. I can make a dial label with your information at no extra charge on this GEC format or the standard GPO. Please tell me in check out instructions what you want.
