In the latest ASMIC Trading Post (Oct-Dec 2019) starting on page 39 is a great article on ATC (Air Transport Command) insignia by David O. Hill. I was hoping it might answer a question I've had regarding the authenticity of the below grouping of ATC insignia I purchased rather cheaply at a flea market a number of years ago. These wings and the cap piece are not bronze like the genuine pieces are supposed to look like yet these wings have age with wear, patina and one clasp is missing the inner rotating piece that you frequently come across on WW2 era flight wings so I don't think they are reproductions. The pins are of the type that only open up halfway. They aren't hallmarked unfortunately and they have the same coloration as normal USAAC flight wings. They have never had a bronze finish. So my question is did the ATC only wear bronze wings?
