I recently came across this Republic of China Air Force (ROCAF) officer's uniform grouping and would love to get a "Legit Check" from the experts here.

 

The group includes the visor hat, tunic with original belt, and all insignia. Key details noticed:

 

Chinese Pilot Wings: Hallmarked "N.S. MEYER INC. NEW YORK" with the shield logo. 
 

Collar Insignia: Winged propellers and rank bars

 

 

I'm particularly interested in the authenticity of the Meyer wings and whether the grouping looks like a consistent late-WWII or early post-war set. Any insights on the manufacture or potential history would be greatly appreciated!

 

 

 

here the rest of the grouping 

Very cool!  Can you get a clearer shot of the wing markings?

The bullion hat badge is Chinese Civil War era (1945 - 49).  The visor hat should have sunburst buttons.
