I was just surting and came onto this website. It seems to have some stats of pretty rarely noted planes but I wouldn't have any idea how accurate it is. Anyway here's the link enjoy. Warbirds
The site is relatively accurate, the data it has for the planes I've researched in the past are the same, seen the site before, kind of like it, he's put some good effort in it. And it's normal that some data deviates from other sources' data, I guess the author hasn't enveloped himself in each plane to a similar extent. Anyway, compiling such a list with such info and such relative detail and a good model history draws up time and energy, it's not so strange that sometime he forgets to check another source, or maybe he only had a single source at the time, or maybe the most reliable source... etc etc... reasons a plenty <Z> <Z>
