The Fiat G.50 AS serie 7 made its first flight81 years ago. Upgraded from the original G.50, the version 7 fought during the Battle of Britain and during the North African Campaign. Its main opponent in combat was the Hurricane, in which it was outmatched. http://pbs.twimg.com/media/FCYQgyrWYAcNFjj.jpg
