If I remember rightly, Dan-Air only had two A300s at any time - NA was borrowed from Hapag-Lloyd and then NB and NC followed a year later to replace it.
Unless my memory is also playing up, only the first of the Orion A300s was painted and the second stayed in a hybrid Lufthansa scheme (which was pretty austere) from beginning to end. I think it was ZK which was painted - it looked great in Orion colours.
