That’s easy, SSM, MTK, Q Kits, Worsley Works, Model Irish Railways, Provincial Wagons, in fact just look in your ‘Aladdin’s Cave’ of Irish related items and the answer is in front of you. You could always ask for pictures of made up kits from members rather than just showing unmade kits.
Thanks again for this invaluable thread, I have learned a lot from your postings, if fact it has become the definitive reference point for Irish Models.
