Bradford City Transport 834, LHN784, a BUT9611T with a 1962 East Lancs body.
This was one of the few third hand British trolleybuses having originated with Darlington as their first double deckers. They sold them to Doncaster who in turn sold them on to Bradford in 1960 being rebodied by them in 1962.
