"F6F-5 Hellcat. Cockpit: FS 34151. Later a/c with BuNo's higher than about 80000 had the interior above the consoles in black Any F6F with the rear windows will have the rear fuselage in Light Gray. (Grumman Gray Take note: those building David McCambell's Minsi III.) The inside of the engine cowling could be Light Gray, Interior Green, or Zinc Chromate Yellow FS 33481, respectively according to production batch. Later F6F-5's may have had a Flat Black cowling interior ahead of the baffle seal between the front and rear cylinder banks. This was most likely done at overhaul. The remainder was Interior Green. The inside of the fuselage on the F6F-5 without the windows would normally be FS 33481 ZCY. Very late a/c with BuNo's in the 94000, range had Interior Green fuselage interiors and black upper cockpits. This is exactly according to the USN specifications at the time. All other areas of the airframe that were exposed to weather were painted Glossy Dark Sea Blue, ANA 623. Remember on all of these a/c the general rule is that the wheel bays, landing gear struts, wheel centers, landing flap bays, etc. are the under surface color. There should be no Interior Green visible on the exterior of any factory finished F6F-5. No F6F-5 aircraft were factory finished in the tri-color paint scheme. Note: ANA 623 is not FS 15042. FS 15042 is an FS 595 color that is close too, but not the same as ANA 623 color used during WWII. Although the variation is very slight they are different."
