By all means, Anthony. Anything that anyone wants I can research if I don't know; as I said, I have access to enough information for most things. The one thing I might be scant on is exact dates when a particular loco or coach 9or anything else) FIRST got such-and-such a livery, but if one was modelling, say, a period in mid 70s, and wanted five 141s ontheir layout, it would be fair to say that three would be brand new "supertrain livery" and two would be black'n'tan; oneperhaps very shabby looking, the other not too bad. But which loco numbers? A purist would need to look at an IRRS journal,for example,of the period to see that loco 14X was one livery, while 14Y and 14Z were another. But i would have the details of how they were painted. If you know what i mean.
If I get time over the next while (though the May Tour is approaching, and the DCDR accounts have to be finished!) I will try to get details of CIE diesels from B113/4 up to 071s put together insome sort of fashion suitable for a reference table. As and when I find info about anythiong unusual pertainingto an individual loco I will add that. Steam likewise; I have details somewhere of exactly which steam locos CIE painted black; there were only a dozen or maybe 20 altogether, and anything painted black was well past 1950. I also have details of which locos were painted green. Not just immediately to hand but I can dig it out.
Coaches - same sort of concept. There were four variations of the green livery, three of them pre 1955, and several exceptions notably on the West Cork system. In black'n'orange/tan days there were minor variations and interesting details, such as the fact that only a very small handfulof six wheelers ever got the black and tan livery, and all thus treated were full brakes. Wagons throw up interesting details as well, such as a standard CIE covered "H" van in all over dark green at one stage (not sure why!).
We also have examples of vehicles "skipping" a livery, such as ex-GNR brake third 114 (formerly in RPSI ownership, may be scrapped now(?)). That coach was the last passenger carrying vehicle to carry GNR brown/teaky livery, lasting thus to about 1966, when it was painted directly into orange and black, never being green.
So if anyone has thoughts, suggestions, or enquiries, feel free......
