Hey, I have one for you, if you'd like to make a cap & jersey: Vincennes Velvets. They played in the Class D Mississippi-Ohio Valley League in 1951 and 1952 at Nehi Park in my hometown of Vincennes, Indiana. This is the only picture I could find. I remember seeing a color picture of their uniform years ago, and seem to recall that the colors were pretty similar to St. Louis Browns colors - mostly brown, with a bit of orange.
If you can't make it, or aren't taking requests at the moment, no big deal. But if you are, I'd appreciate it. Either way, thanks!
