F4U-1, -1A, and -1D Landing Gear Colors

[Juggernut]

For those that may know, what color were the main and tailwheel struts painted on the F4U-1 series of Corsairs?  I'm mostly interested in the very early production raised cockpit corsairs (-1A's).  I've read Dana Bell's 2nd book on the Corsair and it says that Chrysler had a lot of grey paint left over when the color was switched (to the best of my recollection) but what shade of grey?  Contemporary photos indicate a neutral to relatively dark grey but if it's an AN number or a certain shade, I'd like to attempt to replicate it on my -1A build.  I don't think non-specular white is correct but again, I just don't know.  If there were different paint color options then I'd like to know that too.
