Chevrolet did sell a lot of trucks to the US Military and painted them Army olive drab color at the factory. I have the Indianapolis body plant blueprints for the 1935 open cab truck supplied to Artillery Corps (same as shown 75 years of Chevrolet by G. Dammann page 119). I believe I sent you production figures for 36 but they don't separate the High from the Low. The high cab cowl roof & doors were build the entire year on the "single unit" (Panels, suburban & canopy delivery) trucks. The pickup & 1.5 ton cab went into production very early in 36 calander year. The interior of the low cab dash and door trim were painted brown crinkle paint.
