Not 100% sure if this website will have the footage your looking for, but it's worth looking into. I know for a fact he's got footage from the early 1900's World Series and late 1930's, early '40's All-Star Games. Much more footage in the 1950's.

If you should find any '33 ASG footage, let me know. I'd be interested in seeing it also.
Good Luck,
