O.K. - I made up my mind and asked myself why Mount Cook Airlines should have changed their "house colour" in the seventies.
Obviously, their Twin Otter ZK-CJZ, whose 1970 livery already rolled out of my paint shack, also wore this nice light blue, as shown here:

Applied to the 748, it looks like this:


Comes quite close to Ian's livery, eh?
Too bad, I liked this darker blue shade...
Cheers,
Markus.
