Help with dating flannel jerseys

[Chris Counts]

Hi, I'm wondering if anyone could help me out with trying to determine approximately when each of these flannel jerseys was made. I realize coming up with an exact date is not likely. But any help offered is very much appreciated. Also, if anybody has any information of these teams, that would be a big help as well. Thanks, Chris

Nice flannels! The first one (left side) looks to be the oldest...perhaps 1930's. The majority are 1940's and 1950's (Rawlings and Wilson tagging). Most look to be town or school teams, except for the "Angels" as that looks to be PCL or MLB Cal Angels (number on back?).
