Over 2,600 were built, London Transport was the largest operator, purchasing over 700, while British European Airways purchased 64 as coaches.^[4][5] Production for UK market finished in 1955 with the introduction of the AEC Reliance but it remained in production for export markets until the 1960s.^[2]
