Hi there,
There was always confusion about how the tricolour should be painted, ie green leading on one side and trailing on the other.The answer is simple: it is always orientated in the correct fashion, upright and Green to the left, regardless of which side or which part of the aircraft or ship or vehicle it is painted onto.As for painting roundels, it's as difficult in real life as it is on models.It helps if the angle between each colour of the roudel is measured properly at 120 degrees. As Tony will testify, there were always errors on markings on Air Corps aircraft and there probably always will be.Certainly, it wasn't until the Marchettis and Cessnas were getting a lot of overhauls done, close together, than any attempt at standardisation was carried out. Sure, the Fougas retained French spelling and radio codes until they were retired.
