No, I don't think the Carlow kit is still there. The building is owned by CIÉ, so presumably they wanted it back empty.
Dean McGuinness's kit is still in situ in Enfield. He has plans to do something with it, but reckons it'll take substantial investment.
AFAIK, Cuilan has the Biddy Early kit for sale in Templemore.
I don't know what happened to the kit from the Irish Brewing Company in Newbridge: it might still be out there somewhere, though there's now an airsoft supplies company operating at their old address.
