For a change this image can be placed both by date and location. Ex-works Gresley V2 4801 sparkles in the sunshine whilst being turned at Cambridge mpd on May 6th, 1938. She would have arrived there on a running-in turn from King's Cross after arriving new from Darlington where she had been built. Even in my own spotting days at KX in the mid- to late fifties it was quite normal to still witness ex-major overhaul locos working that routine.
