USAF Red Devils aerobatic team

Anyone have any insight?
Seems to be a shortage of real photos of this team in flight, or of the aircraft.
(other than that blurry b/w image)

The team photo (5 pilots) has them standing by any P51, and not a team aircraft.

I am interested in adding this aircraft to my catalog, but without any good reference, its all guesswork.
Which I hate.
Guesswork is the evil that happens at plastic model forums.

Only colour photo I have is this one.
I think its the same as the B/W photo at the above website.
Looks like its pulled from a reference book...anyone know what book?
