As far as I know 1944 (preserved at Downpatrick) came straight off the last Limerick-Waterford set, with the other two from it, 1400 and 1946, going straight to Clonakility Model Railway Village. In fact she very briefly operated at Downpatrick in IR livery before sidelined for restoration, emerging in 2018 in original 1950s dark green (which some did carry, we have photos to prove it, before I'm shot!).
There's a photo somewhere on the interweb of 1944 being hauled to Dublin after.
