Alex, if you look in the C8 parts list, the only colours mentioned are "matte green" and "light stone". In the 1A2 parts list there's no choice of colours for the canvas cover so it was likely just offered in khaki.These would be the colours the trucks were painted at the factory and the SCC2 brown would have been applied in Europe. Chances are the frame on your truck never got the brown paint. My HUP got repainted blue by the RCAF but they just closed the doors and painted it. The chassis and interior remained khaki. When you take all this into consideration a brown Cab 11 would be something like this:
Frame and chassis and engine compartment khaki.
Engine and tranny Chev engine grey or possibly khaki if a military rebuild.
Interior khaki or SCC2 on some repaint jobs.
Seats khaki.
Window canvas khaki with outside painted brown.
Outside of body brown.
Inside of box khaki or brown on some repaint jobs.
Rear seats brown leatherette.
Tilt canvas khaki with outside painted brown.
Radio equipment khaki.
Camouflage pattern in that almost black colour.
If the truck made it to Europe through North Africa you can replace all the khaki with light stone except for the radio equipment and inside of the tilt canvas.
Having said all this, you never see a restored truck painted like this. They always seem to think that a brown truck was all brown.
The picture is a couple of North Africa trucks getting their SCC2 makeover getting ready for Italy. You can tell that they never touched the undercarriage or the interior.
