It was a medal, not per say, but worn by Flying Tigers. I figured that out after you posted the front. »www.diggerhistory.info/pages-uni···sa-3.htm -- I threw out the map a long time ago. Now I follow my own direction!
That site shows Boyington wearing the CBI patch. He never wore it. He left India in May of 1942 and didn't arrive back in the US until July 1942. The CBI patch wasn't created until July/Aug. 1942. So he wasn't there for the transition to the CATF.
Cant be so. The AVG (American Volunteer Group)/(Flying Tigers) Flew their first combat mission in early December 1942, and were disbanded about 9 months later. That medal was not issued until 1944. -- "The world is a book; those who do not travel read but a single page." -St. Augustine
