This is a lovely little telephone. It is known as the compact. I have upgraded it with an electronic microphone an alpha numeric dial face and a chromed dial. It has been stripped down and reassembled after each part has been cleaned and polished. This model has no internal bell and so it comes with a flashing warbler as can be seen in the last picture. Simply plug this into the telephone wall socket and the telephone into the warbler and away you go. These dates from the mid 1970s to the early 1980s. It is fully tested to dial out and receive perfectly. I can make a dial label with your information at no extra charge.
