WWII Aviator Flight Wings Pin and Army Air Forces World War II Patch

Vintage WWII Military aviator flight wings with propeller pin. This pin came from a set marked 10K Gold Filled. The last photo is the original box of which we do not have anymore. Box NOT INCLUDED. The propeller is a silver tone but not marked. There is no patina on the gold or silver parts, but there is on the fasteners. Please see photos. The pin has the words "Acid Test" on the back. The patch is from WWII as well. The ultramarine disk represents the medium in which the Air Forces operated, and the white star with red disk was the identifying symbol of U.S. Army and Navy airplanes. (The red disk was removed from aircraft markings in 1942 to prevent confusion with Japanese insignia.) The golden wings symbolize victorious operation. Although the patch is no longer worn on Air Force uniforms, the design appears on U.S. Air Force uniform buttons.
