tiny unknown wings, anyone know what these might be?

There are no hallmarks on back.

The center emblem is missing

Thanks, I thought there was a part missing there too but wasn't sure.

 These look like sweetheart wings. The center piece was probably an upright propeller or a service star. Miniature wings were worn on the garrison also, either way neat set of wings.
