Ok, got the upper colors down, now for the undersides. From what I can find (and understand. My Dutch is schijten.) the Buffalos should have NMF undersides. But the museum piece at National Military Museum, Soesterberg, looks white/ pale grey. Also some period photos/ video it looks white/ grey too. Were the aircraft painted by Brewster? If so, I’d think they’d’ve used Dupont equivalents like on RAF contact stuff. DuPont made a “Sky” equivalent that was off white.(like FS36622) Also, the Soesterberg one looks like the wheel well bays in the wings are aluminum but the areas for the wheels are the underside color.Yes? No? Maybe?
