A Taste of Honey
(1961, Rita Tushingham, Dora Brian, Robert Stephens)
Then-new Manchester 4586 (4586NA), a 1961 Daimler CVG6 with Metro-Cammell body was used in both internal and external shots. (thanks Kim Rennie and Jon Price).
David Beilby notes “It runs to Castleton, which for the purposes of the film is in the one in the Peak District, but for Manchester's blinds it was the one between that city and Rochdale.”
Bob Wingrove notes that filming took place in Salford, but Salford Corporation refused to provide a bus for filming.
Also glimpsed are various buses and a singledeck tram on the front at Blackpool:
Malcolm Crowe advises the bus garage overlooked here is Stockport (Mersey Square) seen from the rear. The buses are North Western buses on layover.
