The United Kingdom's General Post Office (GPO) had a number of telephones that were provided by them for connection to their exchanges. Until 1982 the GPO had a monopoly on the provision of all telephones within the UK and so the range was limited.
Completely original with original handset and connecting cords. This phone has a number 10 chrome dial with an original enamel alpha numeric number plate. Very hard to find in this condition with no damage.
