One picture

In Squadron/Signal’s Air War over Southeast Asia, vol 2, on page 36, there’s a photo of “A pair of A-37s over South Vietnam during their first combat mission in August 1967. This was during the evaluation period for the A-37, and these aircraft carry an unusual blue/grey and white camouflage scheme.” The aircraft are 14517 and 14519. To my eyes, both appear to be blue overall with white or pale grey patches on the upper surfaces only.
There are other photos out there somewhere…
