This model is very sought after and now widely copied due to the great design with the dial under the base. This is the genuine article and is in very good condition as you can see. I am not certain of the date but around the 1960s. It is fully working to both dial out and receive. This model was not made with an internal buzzer and so we have included a plug in sounder with a light that flashes as well. These came in all different designs and colours and some are very rare. I very nice piece of design and very modern for its time. BT land lines will work perfectly but cannot guarantee other providers although may well work fine.
