This was one of the participants in the Trans Lancs Historic Vehicle Rally in Heaton Park, Manchester in September 1996.
It's an ex-Manchester City Transport 1969 Daimler Fleetline with a Park Royal body. A note in the programme of the event said this about the vehicle:
Daimler Fleetline, Park Royal Body NNB 598H
Entered by Hycote, Royton, Oldham, Lancs
Former Operator - Manchester City Transport. Hycote recently purchased this vehicle to save it from going to scrap. The company intend to use it for exhibition purposes but retain the exterior vintage livery of Manchester City Transport. The vehicle has been exposed to weather for 5 years, hence the poor paint finish.
