Hope you like the uniform. It is not an old one. Here in the town I live in there is a Historical re-enactment weekend every September. I have a collection of antique pocket watches that I wanted to display. The requirements for exhibitors was that they had to have some sort of "period" costume. The first year I just had a white shirt, black pants, overcoat and a derby.
The next year I got the idea to make a vintage baseball uniform. Of course being a fan of St Louis, especially the Browns, I worked up a late forties number. It was pretty crude, but was a hit. Things took off from there.
I have several Browns uniforms along with Cardinals. A couple of years ago I branched out to other teams. Mostly trying to find odd ones to show what some of the crazy things they used to do. I think the 1939 one is my favorite, though!
