One thing that has always puzzled me is why the RAAF painted Fin Flashes on the rudder on early Vampires. Some Winjeel and C47 also had this odd position. Never seen it on RAF aircraft. Did the RAAF call them 'Rudder Flashes' or did the painters not know what a fin was? I know, in the overall scheme of things who cares, but I'd love to know why. The picture above has the correct position but many Mk31's had the markings on the rudder.
