World War I Pilot WC Link Unusual Back Sterling

The wings that are shown are a museum quality reproduction of wings based on a design by the WC link Co. but the actual maker is unknown with a very unusual back system. The Pilot had two holes in his uniform and the hinge was placed in the holes and held in the wings in place. This museum quality reproduction is made of  Sterling Silver with the letters US gold plated. While not an original here is a chance to get one that is sterling silver.
