When the mk2s came from the uk they were all in undercoat, livery undecided so when they decided dull orange the coaches were paint and loco's followed,so the CIE 141 loco's should be near same until 84 when mk3s came and 071 got repaint and a more orange was used.
Re the above post I think it's very smart as the person in question does not own a 071 was just asking to see loco's with both CIE liverys.
