Questions:
1, did I miss any important aircraft type (including prototypes)?
2, what I noticed is that only the Rumanian prototype was low-wing monoplane. Were there any other(s) I missed?
3, I ranked top speed as the most important characteristic of a fighter (at that time). Is this assumption correct?

Thanks for your inputs.

Good work Dénes. As well as speed, initial climb rate would be important, I think (if the figures are given). I'm guessing that all these machines had similar fire power (two machine guns?).
