A long time ago, in a living room far far away... there was a boy named TheHighwayStar who received an Irish Railway train set (#00651) for his birthday. He was overjoyed, and to this still has this train today (albeit in much lesser condition–notably a tender coupler that was once Gorilla-Glued back on in panic!) He has but the loco and coaches today...
Well, that's enough of the third-person referral... in all the back-research I've been doing about this set, I haven't been able to pin down any manufacturing information aside from the product number. Could someone shine some light on this (what I presume is) limited-edition set?
There are some old threads about it. Not much info on it by Googling it.

You may have to change your scale to OO (assuming you model in HO). There are a limited number of listings in the U.K. for Irish Railway stock. I think I would purchase a copy of Railway Modeller magazine and check out the ads. E. Hatton's is an excellent source of European model trains (they willingly ship to the States). Good luck.
