Rare Early 1930s US Air Service (USAS) Officer Collar Insignia

This is a rare early 1920s United States Air Service officer collar insignia. The insignia is a very detailed winged propeller.

Circa early 1920s.

Approximately 1" in height and 1-11/16" in width.

Gold- and nickel-plated brass.

Horizontal pin with C catch.

This is from a United States Army Air Forces collection which we will be listing more of over the next few months. VBEX03 LABEX1/11

8 (Excellent-): The insignia shows very small spots of light wear and tarnish.

As with all my artifacts, this piece is guaranteed to be original, as described.
