I recently bought 16001 - D8400 with a grey roof - wrongly assuming that it would be the loco more-or-less as built, and ideal for my 1958-59 modelling period. I can get rid of the warning flashes easily enough, but as far as I'm aware D8400 didn't acquire the eggshell blue cab end until the early 60s, and removing or covering that would be trickier, so I'm considering a number change. D8404 is the favourite, working on the hopeful assumption that Heljan had a photo to hand when they gave their model of that engine a grey roof (albeit also with yellow warning panels). Of course that doesn't mean it had a grey roof in 58-59, but so far, after consulting numerous books and picture libraries, that's the best I have to go on. Has anyone seen a photo of that or another Class 16 with a grey roof, eggshell cab end, and no warning panel or flashes c1958-59?
