Seeking help identifying old caps
 

I just picked up a nice lot of old caps, presumably from the minor leagues in the 1940s and early 1950s. I'm trying to identify the teams, but the only one I'm relatively confident about so far is the "H" cap, which I believe is from the Hollywood Stars, in part because the name "Haak" is written under the bill, and Howie Haak was a coach for the Stars. The seller suggested the "E" cap is from "Erie," the "CR" cap is from Cedar Rapids and the "M" cap is from Minneapolis, but I'm looking for more evidence.

The most curious one here is the "B" cap, which resembles a 1938 Boston Bees cap. The seller believes it comes from Japan.

Any feedback or insight is very much appreciated.

Thanks,

Chris

Here's a new more images ...

pretty sure the CR is Cedar Rapids. i have a stack of old midwest league programs I will look through to see if i can find a match.
