As promised, here are another couple I've dug out of the pile, both dating from the spring of 1991.
First, 47 583 County of Hertfordshire passing Royal Oak;
and second is 47 452 Aycliffe at Ely. This shows one of the many variations that can occur, even with supposedly standard liveries, in that the 7 and 5 are sligtly larger than the rest.
