Thanks for the link, Al. What I glean from it, is that the '39 rule was so vaguely written that "anything goes'. The '40 rule calls for two code letters, roundel, one letter identifier in that order on both sides of the fuselage, but then states "or vice versa" which confuses the whole issue once again. As a modeler then, unless you're building a replica of a specific aircraft with period photos of both sides of the fuselage to document the markings, either order is equally valid for the right side. Now I can finally sleep. thank you.
