This is a superb job. It would worth, perhaps, a new thread to identify RTR locos or easy-to-make loco kits which could be kitbashed to represent Irish prototypes. We're all aware of, for example, numerous LMS, BR, or other 2.6.4T locos which have been turned into very credible looking NCC "Jeeps". I saw - somewhere - pictures of a brilliant looking GSWR "J15" wise origins were, I think, a Hornby loco of LNER extraction. There's the LMS "Jinty", of course, and the "Woolwich", and perhaps a Brighton "Terrier" might provide the basis for GSR Nos. 90 or 100?
Any more?
