maker,
From what I understand, the 239 and 339C/D used by the Dutch were close enough in performance that the 239 does make an adequate stand-in. Incidentally, HTC apparently still considers the Brewster an American bird on the AHWiki.
jimson,
The F2A-3 saw action at Midway.
I stated this in the Brewster thread on Aircraft and Vehicles, but the best way to cover as many variants as possible with the fewest aircraft would be:
B-239 - Serves as the Finnish 239 and the Dutch 339C/D
F2A-3 - Serves as the US F2A-3 and British/Commonwealth 339E
