When I was a kid I knew that my dad still had his first baseman's mitt from high school. We brought it back out in the mid 80's. It was a 1941 Rudy York model. It had three separate "finger" looking sections to it. It was about two thirds the size of today's standard fielder's glove, but was the biggest thing ever seen back then. My dad let me use it and I brought it out to the bleachers to show my friends. They nicknamed it "the claw." I had it out there for a few games and it paid off big. I caught a line drive homer off Dave Winfield. If you know how Winfield hit his homers (screaming line drives), and that there was only the palm to catch the ball in, then you can figure out that my hand hurt for not just a few hours.
