31273 passes the site of Knighton Crossing (near Uffington) on 17 August 1978 with the 3C07 15:33 Paddington to Swansea premium parcels. This is one of my very earliest railway pictures, which explains why I took it from the wrong side for the light! At least it was taken on Kodachrome 64, rather than the awful Perutz C18 film that the camera shop sold me with my first camera!
