Thanks Guys!
Robert, I used about a 50:50 mix of Gunze Sangyo H340(field green)+H319(light green). 'Post shaded' with Tamiya Smoke, and high-lights with original mix + a little Gunze 'Radome' tan.
Paul, I loosley based it on a photo of a vehicle that had the same OD/Khaki bins, mostly because I liked the colour variation. It was a 'show' vehicle, but I suspect these areas were repainted to put on a new call sign number, and they just used whatever paint was handy.
