LNER J38 0-6-0 No 65903 Kinross-Auchtermuchty goods leaving Strathmiglo in the very early 1950s, the leading coal wagon is still in Amalgamated Anthracite Association livery and there is a LNER van at the rear of the train still in pre-1936 livery, however the loco got its BR number in February 1950 so I suspect it is very close to that year.
