To avoid a super long post I made a chart. Red is completed and uploaded, blue is planned but not started/finished, and black is personal projects that were either a joke or for personal use.
There is also a gaggle of color profiles below this, mostly for the Fi-156. The He-111 skins need a bit of history research done, only color profiles/pics are given (He-111_1 is an anomaly, the correct skin is shown on the skins page but not the game).
The B-17 was a planned re-skin of an existing plane that I never actually did anything with.
Edit: There are several folders missing for the P-51B but I can't find them anywhere. They most likely don't exist but all were of submitted skins.
Edit edit: There also seem to be a few P-47D-25 skins missing but they have the same story.
