"BY GEORGE HES GOT IT!"
The water crane is very much my memory. The green on the site Stewart led me to is what I imagine things must have looked like when the painter was putting his brush away! Not the green I remember from "Haringay West, Finsbury Park" etc. We seldom went out as far as "Hertford East" so I'll take your word for it.
The Railmatch cream will do nicely, I suppose if I needed even more faded green a drop of white mixed in might do the trick.
Very impressed with the photos of your railway. Have you posted more that you could signpost me to?
Very many thanks,
Kind regards
David.
