This is lovely example of a GPO dial Trimphone. It has been totally stripped down and re built after each part has been cleaned and polished. It has been fitted with a new handset curly cord, an electronic microphone which is essential on a Trimphone as the small carbon granule mics were not very good at all and crackle and hiss and a new grey line in cord. This has been set up on a special line simulator and then tested on our own BT land line to make sure it is working perfectly to both dial out and receive. I can make a dial label with your information at no extra charge.
