Kev I've got a Warbird Tech book that is specifically for the Spitfires. Only problem with it is it has the wing panels for the majority of the birds but doesn't have the complete side fuselage panel lines. The one thing it does have that could help out alot is it the actual spars for the wings, main fuselage and the empennage.
This could help out alot when it comes to placing rivet lines and panel lines. If we used real photos with extreme weathering or closeups would could very easily place the panels correctly over spars. Then with that done place the actual rivet lines correctly on there.
I'll see what I can do to scan some of those this weekend for referrence.
I don't have anything on the Mossie though. Sorry bout that.
