Glenn, is this plane just not painted or is a one-off of some
sort? Also, what are the window-looking things on the right
engine nacelle? They look like passenger windows but that
can't be right. Thanks.

Its painted, very flat black ( IIRC: its called Ironball Black
). the lighting conditions indoors is the reason it looks that
way.

Thanks, John. I agree that these openings would be much less
apparent with the black paint.

The "windows" are the engine airflow bypass doors. fore & aft
thier function and controls and controls are detailed in the
flight manual. Page 1-31 thru 1-47

Here is an paragraph taken from the Manual on the bypass
function.

Interesting. I would've thought that the flight manual was still
classified but this makes most interesting reading. I suppose you
knew it was already there or it'd be a daunting task to find it in
what I would think is a thick book.
