bodied AEC Swift in
Golders Green in April 1978 '' route 500 on
Oxford Street in 1976 The largest fleet was operated by
London Transport and
London Country Bus Services, with over 1,500 in total delivered between 1966 and 1972. Bodywork was supplied by Strachans Coachwork (prototypes only),
Park Royal Vehicles,
Metro Cammell Weymann and
Marshall, to basically the same design. The fleet was made up of a number of variations. The longer 36' versions were referred to as
Merlins, and divided into MB (single or dual door), MBS (dual door), and MBA (dual door with turnstile payment for use on
Red Arrow services) classes. The shorter 33' versions were known as
Swifts. There were three variants of this model upon delivery. In the London central area SM (single door saloon) and SMS (dual door with automatic fare collection) classes were painted red. London Country operated green SM-class dual door, fully seated saloons that had been ordered by London Transport. Subsequently, London Transport converted a number of SMS vehicles to conventional one-man operated saloons by adding more seats and locking the centre exit so it could not be used. These were renamed the SMD class, but retained their original fleet number. Neither London Transport nor London Country considered either design to be a success and the first examples were withdrawn and sold, many for scrap, in 1972, after just four years service. Most had been replaced by 1981, mainly with
Leyland Nationals and
MCW Metrobuses. Some were taken by the
Malta Department of Education and remained in their London form apart from a new coat of paint. ==Other operators in the UK==
