Hi all, I have just been in the workshop finishing a few jobs on the National, and thought as I was waiting for a few bits to dry I would have a bit go at the Lister `D` thats sat for years. When I started to strip off a few bits the paint underneath the green appears to be a rather bright yellow. After carefully rubbing down one part, it appears to have, from top coat down, lister green, red oxide primer, bright yellow and a light coloured primer. I was wondering if the bright yellow would have been the original colour ??? Could it have been supplied with say, a cement mixer ??? Any help appreciated.
