According to Curtiss records, they had a Hawk 81. But, I don't really care either way. After the French order, I have NO record of any designation other than a P-40 followed by a letter and maybe a dash number, or a P-40*/Tomahawk/Kittyhawk. The Tomahawk and Kittyhawk are followd by Mk. plus a Roman numeral and sometimes a letter, but no H-X or Hawk-X after the French build.
And all contracts seem to be accounded for.
I mis-typed the 75 instead of the 75P.
That's funny, I never mis-typed before! Ha ha ...
I am NOT digging for this, I just found some data by accident the other weekend while looking for something else. You can rest easy as I'm not in a competition here, at all. I care MUCH more about the engines and props than the airframes. Airframes are easy to modify! Add or subtract sheet metal! Simple.
You should see all the changes on "Strega" or "Voodoo!" Ain't much "Mustang" left! Superficial resemblance only. Almost NO surface is stock! Control surface or other surface.
Engines need a bit more thought. Props even MORE, if you want them to be GOOD. If you don't, what's the point in changing one? :-)
