Thank you to all those who have looked into this for me. Speaking with the owner at Duxford today, I can say he is thrilled with the information that has come to light so far and some interesting leads have surfaced. I think he’s ordered several books as well! The period of it in store at Dyce seems to be the most vague but undoubtedly someone somewhere has some photos. It would be great if enough information can be gathered to reproduce the early livery during its forthcoming overhaul.
