In the Great War we “ALREADY” used it

That is not what I said

The Great War was WWI, the P-40 is a WWII fighter. By the time the Dutch received these aircraft, they were basically dissolved. When their Pacific forces were assimilated into Australia and her allies, the triangle was changed into the Dutch Flag. The symbol is accurate.

I’m also a “sir”—my name is MrMereScratch, after all.

Though we used to use our national kingdom insignia before that (a orange with black border lion)

we have always used it

In the Great War we already used that sir(or madam) I have the feeling y or need to do some more research about us

Yep, 1942 to 1948

As far as I know, the Dutch East Indies-bound planes used their own flag. That’s what the reference pictures told me, anyways.

I’ve seen the triangle applied only to craft operating in Europe.

Uhm…. Mate… our aircraft insignia was… an orange triangle with a black border
