All the ATR72s are (according to Jethros) -200 - or, specifically, 212A - models.
I'm actually surprised that they're repainting the acft in the new "Celtic rings" logo, which (if I'm not mistaken) means there'll be no acft still left in this logo, while there are still quite a few in the old scheme? Wouldn't it have made more sense to repaint these and keep the "Celtic Rings" scheme as their main livery?
Enjoy it while it lasts:

Still, good to see this going ahead and I hope it brings very significant benefits to both carriers.
