Siam Thailand pre-WWII Air Force Insignia

In my relentless pursuit of images and sources for WWII flight insignia from the world, I find that Siam/Thailand continues to be one of the hardest places to research (at least from an online standpoint). Without actually going through government archives, I have only found one image/artifact I know to be from the pre-WWII period. If anyone has anything else they can add, I for one would be most appreciative.

Here it is. An identification booklet to an aviation sgt.of the Thai/Siamese forces:
