This is one of the then current operating PSVs at the Trans Lancs Historic Vehicle Rally in Heaton Park, Manchester in September 1996.
It's a Nottingham City Transport Dennis Arrow SFD with Northern Counties H44/36F body. The 'N' registration was issued between 1 August 1995 and 31 July 1996 so it was obviously then a fairly new vehicle, but the organisers of the event were obviously expecting a different one as the entry in the programme reads:
Dennis Arrow, N.C.M.E. Body, 1995 N401 ARA
Entered by G Clowes, Bulwell, Nottingham
The prototype Dennis Arrow which appeared at the 1995 Bus & Coach show. Vehicle owned
by Nottingham City Transport.
