253 was a much-rebuilt Weymann-bodied Leyland PD2 of North Western and one I remember well as an Oldham depot bus, which implies it was working a duplicate when seen in Bradford's Chester Street bus station on 7th August 1965. Although it might not at first seem a likely choice for the service, the meaty O.600 engine would have given it as good a performance over the hills as the more modern AEC Reliances.
