This is a beautiful example of a hard to find Siemens 310 model. This telephone has been stripped down and rebuilt after each part has been cleaned and polished. This is is fabulous condition and is ready to plug in and go. It retains its original Siemens specification brown braided round handset cord. I have fitted a very best quality D shaped plastic line in cord made by me, an electronic microphone and fitted with a 3.3K resistor to bring the Ren down to one. It has been fully tested on special our special equipment and on our own BT land line. It retains an original GPO No10 enamel faced number dial with a stainless steel finger wheel. I can make a dial label with your information at no extra charge.
