This thread is the right place to search (ask), but it's just too long! The pics are from it, the first two Oct 2009, the third Feb 2009. I have them on my disk but don't find them in the thread right now. The first two pics are from the AMA museum IIRC, you could check there.
But I'd guess you're right that the red trim is on the wing bottom as well. The other pictures show that there's nothing else, nothing on the stab bottom, and only some red on the fuse front bottom. You see the nose landing gear (for that version) as well.
