Incidentally, Kiltimagh (and Cultra and Clonakilty, for that matter) have taken the very non-museum-like approach to how to paint their historical artefacts. Namely, "ah, sure it'll do, its near enough". As IRM folk will be aware regarding the Kiltimagh coach, it never had a white snail and yellow line! That isn't "near enough", in my book anyway.
When people see things in museums, they surely have a right to expect that the thing is properly presented. Any of these errors can be righted easily of course, but why not do them correctly in the first place? It's not as if the information isn't there.
Laziness in this very visible aspect of preservation has pervaded every single solitary preservation outfit on this island. As a result, modellers are misled. I have seen numerous absolutely fantastic models wearing "liveries" which have clearly been copied from incorrectly painted survivors in preservation. You'd never get that across the pond; are we, as an island race, colour-blind? Am I, out of interest, the only person who feels that this is something that ALL of our preservation and museum outfits ought to be a great deal more diligent about?
Just asking....
