Poland's PZL P.11, fighter updated

The Polish Air Force had some highly motivated fighter pilots but unfortunately for them they had outdated planes. The PZL P.11 was the main fighter they used to fight against the Germans. In the short time they fought in the air, they shot down 125 Luftwaffe planes for a loss of 114 of their own.
I've added additional specification and production information for the P.11.
