C820 Standish Junction 11 October 1986

C820 (51512, 59093 & 51500) takes the 'Golden Valley' route at Standish Junction on 11 October 1986 whilst working the 09:27 Cheltenham to Swindon service. Yet again the driver has forgotten to change the destination blind. I wonder if it says 'Swindon' on the other end?
