I find that interesting. Here is a pic of my inner fenders. I bought this truck from a family that had owned it since 1939. At some point, they gave it a rattle can black paint job. As you can see, the inner fenders are green which was the original color of the truck. When I posed this question, I wasn't sure what color the fenders were and thought they may have been black. After reviewing some of my pics, I'm pretty sure the front fenders were also green originally.
So.....????
