Episode: Killer
Has an appearance by 616BYP, a bus full of dummies!
Mike Lloyd explains "the little bus is a Commer HX441 with bodywork by Owen, and is certainly owned by or ex Molins Machine Company of Deptford and Saunderton, Buckinghamshire. Molins ran a network of staff bus routes,
but they were fully PSV-licensed, so presumably the lucky staff had to pay for the privilege. Most of their buses were Bedford SBs but there were three or possibly more of these little Commers. All the fleet had bodies by Owen, better known as a builder of gown vans. The basic design was externally identical to the Mulliner metal-framed bus body of about 1957, shortened for the Commers of course. The livery was cream, later yellow, and internally although buses, the trim level was nearer to that of a coach with much moquette on side panels, etc. As far as I know, none survive today."
