Hello Again Andréa,
Well, this site haves many mistakes.
The Nieuport 24bis you show comes from a pictures stored in greek historical service, taken in Gorgop for an inspection of general Franchey d'Esperey or something like that.
But this plane do not belong to escadrille 531 : I have all the serial numbers of the planes given to the greek in april 1918 (you can see that in website
Société Nieuport ) and 4613 is not there... The initials TP belong to a pilot from french escadrille 507, Pierre Tihy. This is very likely that it was his plane.
If you want to put in your game a plane with greek cockades that we are almost sure flew operationnaly during WW1, make the Nieuport of Alexandros Zannas. I have a bad picture of him near a Nieuport, you may have it because it come from the greek version of the history book you talked about. The Nieuport is silver, with a round fuselage, but we don't see the tail (24 ? 24bis ?). The wheels seem to be colored, and it haves a big "5" in the fuselage. We're not even sure it was the plane he flew, as squadron leader he may have flex the "1" instead...
But, to make something almost historically correct, as far as we can say :
- Silver Nieuport 24bis with greek cockade and greek tail.
- Red "5" on the fuselage.
- Wheels colored in red or tan.
- Serial number... well, for exemple 3706, from a 24bis of escadrille 531.
Contact me in private if you want colors on fighters used in the macedonian front, from french aces
Dieudonné Costes or Basile Sauné, or even serbian pilots.
