FYI unless anyone questions the accuracy of the roundel changes (check them out here...
http://www.users.on.net/~jscones/markings/markings.htm ) I will release this add-on in the next few days.
Whilst I've done my homework and am quite certain everything is right, I'm happy to be corrected by anyone "more in the know" about a particular country.
Again, if you plan on using these, I strongly recommend that you get SSB's multiple roundels for aircraft first (from
