So, I'm posting here the early lists made then, to get an overall picture of what every considered country would look like. It is a quick/first draft: it would have been refined, completed, corrected, ... more thoroughfully later had the countries been selected.
Yougoslavia here. The document was in French, but it shouldn't be too problematic ...
Unfortunately, since the Southern Front was quickly dropped in favor of Scandinavia, Southern countries left over hadn't their plane selection made at that time.


Although neutral IRL, Yugoslavia would have been Pact-affiliated, just like Sweden with NATO in ALB.
