KiwiZac,
The Smithsonian book mention's the Australian War Memorial's D.Va as it was restored from an original as well before the Smith's was. I believe these are the only two original aircraft in existences. I followed your link and WOW, love it! More great photos and information, very much appreciate the link, pictures are worth, well you know the expression. I will most defiantly be spending sometime on their site to see what insight that comes to light.
Thanks again Sir!
