Nmp. Don’t remember seeing this rather poor photo before.
Looks like the late, lamented BD1, destroyed by arson attack after many years in preservation. Its two sister vehicles are both preserved, fortunately.
BD1 was based at Preston Depot, and was sent far and wide to recover dead machinery, even when itself quite elderly
This photo was taken in Fylde Road, Preston, in 1974:
