Oregon State College Wool Cap/Hat/Beanie (c. 1930’s-1940’s)

Here is another vintage wool Oregon State College hat from what I’m guessing is the 1930’s-1940’s.  I have several hats that look similar to this but all are slightly unique.  Many are reversible, but not all.  One of these days I’ll need to take all of them to a hat historian (is there such a thing?) and figure out how old these are!  Or I need go to through yearbooks and see if I can find pictures of fans wearing these hats to better date them.
