Very nicely done Dave, I have a book called Canadair CF-5, Freedom Fighter by Anthony L. Stachiw which says in the chapter about model kits available of the F-5, that although the Airfix kit is rather basic, it's the most accurate of the 1/72 kits (for an 'A' variant that is). I have to say having worked on a 1:1 scale one, how the kit goes together is pretty much how the real thing's parts get assembled.
