Hi All,
I have spent some time going through all my extensive E train material, official docs and so on, and have found that the paint ordered for E train was from Wilkinsons of Rotherham, internal code R478, so the one thing we can now say for sure is, she isn't BR blue.
When the train was repainted in 2002/3 we had to use a close match as the exact mix for R478 had been lost in time, so Wilkinsons supplied us with the very nearest colour match of the train at the time, although slightly darker to take into account may years of fade.
Id like to say, Ive added that to the mix, but that would be a pun lol.
