True, it could have been overlooked, but there is a lot of information on aircraft losses around. Much of which was actually due to the German penchant for fastidious bookkeeping. As I said, I haven't looked into this myself but others have. There is an extensive Loss Register (
https://www.verliesregister.studiegroepluchtoorlog.nl/) and you can check which Fw190s ended up on Dutch soil.
