Pierre Clostermann mentions, in his book "The Great Circus", he saw a
dogfight between a Spitfire of his squadron and an FW 190A-6 piloted
by a certain "Major von Graf", nicknamed "Donald Duck" by the Allies.
"Big Show" gets better each time Pierre re-writes it. He is the only man I
know that has a better memory at 75 than he did at 25 - his original 1950s book
has many changes in the current version, but I don't think they should all be
considered 'corrections'.
The Germans painted some captured machines overall yellow - no FW 190 was flown
in combat in that coloration. How do I know? Well, Graf never mentioned it
(he survived the war), NO photos have ever come to light of it, although most
of Major Graf's aircraft were photographed - its unlikely that his 'normal'
190s were photographed, but not this "donald duck" (what a joke). Unlike WW1,
when the Germans were confident enough in their fighters that they painted in
bright colors to actually encourage a combat; by 43-44, German fighter pilots
were on the defensive and certainly not flying around in primary colors,
looking to pick a fight. Yellow identification panels are one thing - overall
yellow is not the same.
The Fw was, according to his book, painted in overall bright yellow
scheme and, curiously enough, I couldn't find any other reference to
that specific aircraft,
Occam's razor - if no one else ever heard of it, but Pierre 'saw' it (like he
'saw' a Do 335 in flight, at a location where none ever flew), there is your
answer.
I guess such an exotic aircraft would be mentioned
at least in one or other book, specially considering it was flown by
the CO of the Jg.2.
Yeah, that does raise a red flag, doesn't it? No models or decal sheets are
sold of this odd a/c, no profile drawings exist, etc.
Does anyone have any reference material, picture
or whatever about this plane?
Only Pierre.

Contact him and ask - he answers questions through his
biographer, Mr. Perales.
