Thanks JH. Hard to tell if 401 was green or grey as she looks black, probably due to the fact that it had not been cleaned for 6 years! The first time I looked at the book, with little knowledge of anything Irish, I believed that the woolwiches had been painted a light blue! It seems the must have got sun bleached( in Ireland ?) as the green had gone this colour over the years. I knew there was something strange about 461s livery. Looks a bit too light
