Patrick,
I pulled out my '51 Salesmen Truck Data Book and looked at the paint chips in the back. Given the limitations of matching colors on a computer screen, that truck looks very similar to Cape Maroon. If anything, the truck is a bit lighter than my paint chip.
I am restoring a '50 COE that was originally black. I worked on the fenders and decided to try Mariner Blue. I had the paint shop mix up a quart, based on the PPG numbers in the Tech Tip and the color matched my chip very well. If you want to stay original, you could try that, or just go with anything that suits your fancy.
