Hi Mark.
Andreas and me covered this in out recent book (Just check the chapter on II./JG 77).
Seems like the order to use yellow recognition bands (the size and placement of which diffferent from the later Eastern front ones) reached Norway as well.
Here are a few photos from the book showing these bands and their position (in the centre photo the upper crosses are covered by canvas, but note the wing tips - same aircraft is seen in the top photo):
Best regards,
Kjetil
