AEC Regent III

The AEC Regent III, also called the Regent 3 or Regent Mark III, was a double-decker bus chassis built by AEC from 1950 to 1956. It was mainly made for operators outside London and overseas, usually with AEC's 9.6 litre diesel engine, a Wilson preselective gearbox and air brakes, and bodies came from builders such as Park Royal, Metro Cammell Weymann and Charles H. Roe. London Transport bought 76 low-height versions with Weymann bodies as its RLH class, used from 1950 to 1971, and the London RT type, first built in 1939, was a Regent III design of which 4,825 were built. The AEC Regent V succeeded it, and the last were supplied to Reading Corporation in 1956.
