Help with ID of 'Silver Wings' Pin

[76r]

I need help identifying this 'pin' and would greatly appreciate the input of you 'experts' here in the Milsurp forum.

It appears to be made of silver as it tarnishes, and cleans up nice with silver polish. (It appears brass in the photos due to lightiing.)
My G-Grandfather was an RFC pilot in WW1.
This pin was found in a drawer in his home after his death. I remember seeing it in my youth, but never asked him any questions about it.
The 'assumption' was that it was his from the service. ???

Any opinions?

Pretty sure it's from the USA.

The original Army Air Service had it, as did its successor the Army Air Corps. The USAF Academy still uses it.

Sorry, no idea as to precise date or value. Not sure as to the small ring at the bottom.

As Atom said, it's American. The design is the same as the Army Air Corps and later USAF collar insignia but with the ring on the bottom, it's likely a sweetheart pin. I would say WWII-era

I thank you both for your assisstance.
That is sort of what I figured. I recently ran across a picture with a similar pin and it was on a US uniform.
This confirms my suspisions unfortunately.
Thanx again.

I wouldn't be too downhearted. It's a neat bit of history and I'm sure somebody would be delighted to get it.

It is sweetheart jewelry, given to a mother wife/girlfriend, or purchased by same at home. Note the ring at the bottom of the propeller. A jewel, or something would be suspended from that ring. Also, it appears to be a stamped brass construction...the light stamped construction indicates it is not a military issued piece of insignia.
All of the WW2 officers prop and wing insignia were a heavier cast brass, generally with a makers mark on the back. Common makers were Amcraft (American Metal Crafts), L.G. Balfour (marked LGB or Balfour), N.S. Meyer, Amico (American Insignia Co), A.E.Co.(American Emblem Co, Utica NY). There were other makers which are difficult to find, Bailey, Banks and Biddle, Luxenburg-N.Y, Luke-Melbourne, Fox, Dondero, Josten, just to name a few.
Nice little piece of insignia you have.
Cheers

USAAC/USAAF sweetheart pin. Quite a variety of those pieces, but yours could have been something like this at one time:
