Designed by Bruce Martin, some 11,000 were installed between 1968 - 1983. Like its predecessors the phone box was made of cast iron with large glass windows on three sides. The large windows made it vulnerable to mindless vandalism that plagued the nineteen seventies.
This was the last telephone box design from the General Post Office as it ceased to be a government department under the provisions of the Post Office Act 1969, the Corporation was split into two divisions - Posts and Telecommunications - which thus became two distinct businesses for the first time. The Post Office ceased to be a Government Department on 1 October 1969 and was established as a public corporation under the Post Office Act. Making it a nationalised industry similar to the Gas and Electricity supply industry and became known as Post Office Telephones.
