If it can inspire some, and following Greg suggestion for Japan (which start to gave me some idea ), I took a look in one of my Mirage III books and found this list of some Dassault's prospect for the Mirage III/5/50:
The list is missing Finland. In 1961, Finnish Air Force tested Mirage IIIC and Draken A, preferring the former to be acquired due to being a more finished product. Then, the Soviet Union abruptly changed their offering from MiG-19 (which had been ignored as obsolescent) to MiG-21F-13 and that was chosen by politicians instead.
