743 was delivered in early 1949 as one of the last 20 new trolleybuses purchased by Bradford Corporation, none of which were re-bodied. Only licenced on 3 December for the opening of the Bradford Moor service it spent virtually its entire operational life based at Saltaire Depot, only being transferred elsewhere when the Crossflatts - Bradford service was being prepared for conversion to motor buses. Withdrawn from service in November 1963, 746 was placed in store to re-emerge in 1966 as driver training vehicle 062, after which it was de-licenced and sold. It still sports its driver training modifications, and may well be restored as a driver training vehicle for the Museum in due course, when resources permit..
This vehicle is kept at one of the Museum's reserve stores awaiting the completion of its restoration.
It is a sister vehicle to Bradford 746 which runs regularly in service on open weekends.
