Public Holidays in Huddersfield have differed historically from those in Oldham and my recollection is that this is one such occasion. It is the day after Spring Bank Holiday Monday (1st June 1971) but the 65 is working a weekend service as it is also a holiday in Huddersfield. Fleetline 474 was working the 1355 journey from Oldham and carrying no passengers as this journey did not normally run on weekdays!
