W9135E was famous on the WR: https://www.flickr.com/photos/robertcwp/5264054255I do remember seeing Gresley coaches in blood and custard passing through Stratford in the late '50s but they didn't really look good. The Thompson steel coaches always seemed to be maroon though the Gresleys were special coaches (diners, kitchen etc.) so maybe there wasn't a priority to paint them maroon.
