I agree everything you say.
I would add that my father would never have positioned himself as a 109 or Fw 190D 'expert' on the basis of the hours he flew in them at Gablingen after the war. He did have the ability to fly them against the late model 51D flown by very skilled pilots (Elder and Hovde) but who knows what actual condition both ships were in relative to overhauls and specs?
I wonder if he would even consider himself an 'expert' in Mustangs with over 600 hours in them including post war and Korea? He would have considered Bob Hoover as the 'measuring stick' for that standard.
Expert could be in the eye of the beholder..
IIRC your father said that the Fw-190 was slightly better in the horizontal than the P-51 ? If so it agrees completely with other aces have said and all the sensible stuff I've read on the subject. But seeing that you'd have to be accustomed to an a/c before you can get the max out of it your father must have been quite familiar with the Fw-190 ? How many hours did he fly it ?
Anyhow may he rest in peace with all the other aces out there
