Colourful! HEV995B was Eastern National 2817, an FLF6G new in December 1964. Withdrawn in September 1980, and sold on to Ensign (dealer), the bus was with Lager Kitchens by 1983, then noted by October 1986 with The Clown Jewels of Invergordon.
Rob Sly has a later photo on his site taken in June 1999 - it is apparently kept in the grounds of a house on the B817 near Invergordon, still sporting the same colours.
