This is an artist drawing of the squadron markings of the 309th Fighter Squadron as they were flown in the North African Campaign. The aircraft markings WZ were the identifier for the 309th Squadron and each aircraft was further identified by the additional letters as AA thru ZZ. This Spit has the large nose which housed an air filter to filter out the desert dust which caused problems with the engine as well as with the guns.The gun ports were usually covered with tape.This image used with permission from Dennis Kucera, the author of " In a Now Forgotten Sky, A History of the 31th Fighter Squadron in World War2 and Flying Machine Press.
