Hi!
Good stuff to see! Also on the italian markings there is a little confusion. Our official roundel had green outside and red center, the ones with green center are french roundels from imported aircraft, simply with the center repainted. Same confusion on rudders. Italian is G-W-R like our flag. When we received, for example, Hanriots Hd.1 they had reversed colors because of the french origins. Of course, the flag under the wings is wrong, we had wing tips painted red on port and green starboard, also on french design.
I think that also the greek rudder is wrong, it was B-W-B like the cockade.
Cheers!
