Since the aircraft was painted while still sporting the late-WWII insignia, I'd bet on 47 Orange Yellow. Here's a color chip:
FED-STD-595 Federal Standard 595 Color FS 33538
And we all just know aircraft never varied from the color specs, right? Right?
I'll be first in line to buy one of these, Dave. Thanx!
