PRESERVATION UPDATE

■ PICTURE: TONY WILSON
Never a bus, but built by a much-missed coach and bus bodybuilder, this 1956 Harringtonbodied Commer Avenger III was among the commercial vehicles at the Chatsworth Country Fair at the Derbyshire stately home on 31 August. SLO 24 was built for the General Post Office as a mobile cable and wireless vehicle used at sports events to transmit telegrams by high-speed automatic circuits or teleprinters connected automatically to a central telegraph station, where they were received as perforated tape and fed into transmitters connected to international circuits. It was used to demonstrate telex in the 1960s.
