Let's start with the basics...what are the call letters on the fuselage?
It was common practice during WW2 for Fighter Group markings to share similar styles, and the individual squadrons would often use different colors within the same pattern.
For example...a famous P-51 is the 78th FG Big Beautiful Doll, flown by John Landers. All of the 78th had the black and white checkers on the nose, but hte ruddes for each squadron were different colors...black, white with red outline...etc..(I can't remember the 3rd).
Korean War era is a little more difficult, but, if you get me the squadron or group, I'll do what I can to help out.
