Vietnam US Army SF wing Badge Sterling Air Borne

This is a museum quality reproduction of a very unusual wing badge from the Vietnam era made in sterling silver. This is one of the many unofficial badges the SF troops had made in country. This wing is rather unique in that the base wing is from the US Army Air Service of 1919 -1920 era and then had the center part soldered into place. This is the only one of the many SF wings I have seen made this way.
