I'm looking forward to that list with great anticipation. I wonder how I could have missed Luftwaffe aircraft monographies which go that much into detail!

A list provided by Jukka are really basic demands. I wonder how aircraft monography can miss such 'details'.

Then please tell us exactly where all the information above for the Hs 129 can be found - where to go for Dénes and many other among us would love to see that missing material! Do you have the names of the contact persons at those places where all that material can be obtained?

I have never looked for Hs 129, so I cannot tell where the stuff is exactly. Nonetheless, a look into Phil Buttler's War Prizes should reveal histories of individual captured airframes and establishments that tested them. This will provide a list of archives that must be asked for. My best bet will be NA, Kew, Richmond; RAE Farnborough; NARA; etc.

While you are working on that, please also list five or six books where I can find comparative performance curves for different Me 109 aircraft individuals (i.e. different aircraft of the same production type, like e.g. the F-4) at various stages of engine wear and at various weight stages (full tank, full loaded, half full tank, etc); also with cirves for various degrees of polishing, and some comparative performance curves for various degrees of pilot skills regarding trim, propeller pitch etc. Those performance curves will tell the reality - contrary to the clean test flight performance curves, which give us no span but only are fairly clinical. Please list a few books where those "must" performance curves can be found for the Me 109 F-4.

I know of such performance data aurviving for Spitfires for example. Influence of rivets, wear or equipment like mirrors was carefully checked. I cannot say if such detailed data is avialable for Me 109F-4 or any other German aircraft but there is really no problem to get performance curves. I have got both German and British ones for Me 109F-2.
The fact that I have got neither of them from the books is not a proof that those data are not important but that those books are crappy.
Those reports may be sourced in archives mentioned above.

BTW, Franek, you'll find your name in the acknowledgment section in my forthcoming biography on Hans-Ekkehard Bob, which will be published next year. That for the info on Polish aviation which you so kindly helped me with.

Is there Ruy for providing a medium for those informations?
