[Csaba B. Stenge]

Nick has the point. RHAF used the same system (spiral or 1/3-2/3 on spinner) generally because safety reasons on the ground to see, propeller blades were moving or stationary.
Still, I identified one of such fatal accidents in WWII in Hungary, when an unfortunate, careless bloke walked into the moving propeller circle in an airfield (you don't want to know the result - incidentally in that case it was an older type, and it had no paintings on the spinner).
