I'm building a static model of the HMS Vanguard, the Bronco 1/350 scale kit. I know that the propeller (or whatever it's really called) is a top "I could tell you, but I'd have to kill you" secret, but does anyone have any idea what color I should paint thing? I assume the outer ring would be the hull color. But there is a fan-like thing in the ring and sort of star-ish bit in front of that. What is a legitimate color for those parts?
