Greece-Greek pilot's wings pre-WWII

[makedon]

Dear collectors,

Within the past few years I found these identical pilot badges, that seem to be Greek. One of them even has a number on the lower part of the reverse. I am wondering if anyone could tell for sure whether these two examples are original Greek pilot badges. Has anyone seen them before? is there an expert on world pilot's badges?

thank you!

This badge looks like the design used by the French airforce  to me
