AEC 661T

The AEC 661T was a two-axle double deck trolleybus chassis manufactured by AEC between 1931 and 1942.^[1] Based on the AEC Regent bus chassis, over 380 were built for United Kingdom and overseas operators.^[2] Bodywork on early models was similar to that on the AEC Regent motor bus, with a half cab front and dummy radiator, but a full-fronted version was used from 1934.^[3]
