Hi Stig,
A Scandinavian travelling to Greenland to see fjords. Seems a bit like what we call a busman's holiday here in the UK
Now back to the mystery Nieuport serial, I've blown the photo up to higher than 300 % and for me the initial letter remains blurry,but for the remainder I think you'll agree when you return home that the first two numerals are both 8 and that we have a genuine mystery.
Alas I don't have the C&C book,but would it in any event have serials that airhistory.org does not?
Regards,
Clint
