>But you're right, the first few entities appear not to have copied. There should also be Aden & Aitutaki, I believe, to name two more. Newfoundland had full country-level status until about 1950, that's why it's there, I guess. Not sure about Nove Scotia, that's definitely in the "dead-country" status.

I have some Newfie stamps; I could be wrong but I think they joined Canada proper in 1949, before then they were just part of the British Commonwealth. I went looking at the UN website for a listing and there is one but not much more help.
