Joe,

When I did mine I used a combination of the 1:48 Aeromaster Spitfire Stencils (squadron.com), item 148-009, and the SuperScale Decals No. 48-722 (also available from Squadron), for Spitfire Aces. I spent a long time trying to find a font that exactly matched what was used on the spitfires, but found that it often differed from plane to plane, so I finally settled on the 'stencil' truetype font in word. I did all my decals on the computer and was very pleased with the end result. The picture below is after I sprayed some gloss to help the decal sit flat, and before the final flat clear coat over which really sealed them off nicely!
