Stratobat, I will have a look at the Mustang engine cradle colour for you.

Interiors of US aircraft were variable painted in one of the chromate colours but later in the war, certain interior areas on some aircraft left bare metal either to save weight or just because they didn't think it was necessary.
I don't agree with this as it would lead to corrossion on the parts,wings,fuselage etc., wherever the part was used.
I have seen sections of wings,fuselage,etc., that are usually covered with "aly" cladding and they all have a zinc chromate covering on it.
Luckily we have a rear fuselage that is still natural metal outer with the American Star on it and Interior Green on the inside. I would say that the Humbrol Interior Green is the closest colour to this.
