Blenheim MKIV (RAE report "Notes on the dogfight)
Brewster Buffalo (F2A) with Flap and Clean (Exhaustive USN/NACA study on Flap effects on turn performance)

So six or so.. Out of how many planes in WWII?

Maybe.. but like you I have only found about six or seven over the past 20 years of flight simming.. But even if you could find ONE for each plane, remember, the fan plot shows the results at ONLY ONE ALTITUDE! Typically somewhere between 10 to 15kft

Thus it is safe to say that at some point 'we' will have to trust the math (FM) of it all.. As in a calculated value. Once that is done and agreed upon you have to find those that have what it takes to do the test! As noted, based on my experance of testing and reviewing tests done by others, sim pilots typically fall way short of that mark!
