Anybody wanting access to an archive of material & sources on the Brewster fighter in WWII should visit "Annals of the Brewster Buffalo" at Daniel Ford's website (link below). It's the best source on the internet.
Ford is the author of "The Sorry Saga of the Brewster Buffalo: A Flying Coffin to the U.S. Marines, but a Pearl to the Finns" which was the cover story of the June / July 1996 issue of
Smithsonian Air & Space Magazine (vol. 11 no. 2). It is also available in Kindle format at amazon.
