I wonder if any of the Bf109 or Fw190 aircraft of the Experten are still intact...those would be probably some of the higher scoring machines around as far as fighters go...
At the USAFA Steve Ritchie's 5 kill F-4 is on display as for bombers that saw combat you have Diamond Lil at USAF and Strawberry Bitch at the USAF Museums at Dayton Ohio.
There's a company in Colorado Springs restoring a P-38 that had a number of aces fly it.
There's also the forward section of the B26 in the Museum of the Air Force, formerly the USAF Museum. Over 120 ops IIRC.
And, of course, Lancaster 'S for Sugar' in the RAF Museum.
Joe - is it documented that he scored all five in the same F-4?
I would be so suprised that any LW aircraft of significance survived the scrap heaps, ditto Soviet MiGs etc or any US fighter prior to Vietnam..have no idea regarding Britain birds from WWI or II
One that might have survived is Toon's (?) from Vietnam as he was a national hero.
Another possiblity is Rickenbaker's Spad (if original) at Smithsonian.
I know the F-4 named Scat that I saw at DM last year was not original
