'Think I'm getting mixed signals here so thought I'd post and (hopefully) clear some things up. My M37 has a DoD of July 1953. If I look under the hood, I can see a varitable rainbow of OD shades. Outside of the engine compartment, the truck was painted up in (faded) fire engine red with black frame, suspension, axles & drive line components.
I've read somewhere that M37s left the factory with black frames & axles and were assembled with "bright" fasteners. If the frame & axles were indeed painted up that way then how about the following; Springs, shock absorbers, bumperettes, towing pintle hook, frame brackets (cab & bed supports plus the stamped tie down eyes that bolt to the frame) gas tank, drive shafts,
There's probably something else under there that I've forgotten but if that's the case, I can always post again

My goal is to paint my truck up in either USAF Strata blue* or in the "late WWII" semi gloss OD which is what my truck was originally painted when new.
* I know that they (M37s) didn't leave the factory in strata. That was applied by the USAF when the truck arrived at the unit to which it was assigned.
