As you can see this is a wonderful example of the GPO call exchange model telephone. It has been totally stripped down and rebuilt after each part has been cleaned and polished. It has been fitted with a very best all British manufactured hand plaited braided handset cord, a GPO specification round plastic line in with a UK telephone plug socket and a best quality electronic microphone to give perfect speech quality. It retains its original genuine GPO No12 dial. It has been set up using a special line simulator to the required settings and then tested as working perfectly on my own BT line. I can make a dial label with your information at no extra charge.
