The Guy Special was a bus designed by London Transport to replace the pre-war Leyland Cubs on rural country routes. Only 84 vehicles were made.
In 1952 Guy produced chassis for the 84 buses, which received ECW bodywork with a family likeness to the RF. By agreement with the licensing authorities, they seated 26, but were still allowed to be single-manned. Sliding ventilators were fitted to windows rather than the standard wind-down type.
Sixty-five Guys entered service in the last three months of October 1953, with another following in January 1954. The other nineteen slowly entered service with some being as late as January 1956.
