Gear casing colour

Thanks Guys. Nothing like asking the experts for help.

Hey dog;
Testors Model Master paints has an FS # for Gloss Engine Grey, it's darker then Gunship Grey, but I've built Radial engines on real A/C and painted them Neutral Grey and even Dk Gull Grey and they looked really good, it's you option bet there is a color for that shade

As with most paints the exact colour changed with every can. most were a neutral gray. some have been sited as dark gray but i suspect that it was more to oil build up than anything. the crankcases were also a gloss. It was to make easier cleanup of oil and gunk. if a radial was not leaking oil, it was out of oil!!
