CW-21B Interceptor -Gun Metal

This is the CW-21B Interceptor, it's a light weight export fighter the US built in WW 2, though used only as a trainer themselves, which I don't understand. It was used by the Dutch in the battle for Java and held it's own pretty well against even the Zero and against all odds. Though it had all the same problems, last of armor, or armored fuel tanks and a light armerment. It was armed with originally a single .50 cal and a single .30 cal, later it was armed with two .50 cals which wasn't bad for such a small fighter, also having them in the nose meant you didn't have to gear them to a range.
It's turn rate was less then that of a Zero, but better then most fighters of the time and with a climb rate near that of 5,000 feet per minute (1667 Meters per minute, roughly)!!! It could easily out climb most fighters in the world at the time!
