I found this today at an estate sale for $3. There was some ephemera and pictures from a Sailor who was in the Navy during WWII and served on the USS Chilton. There was also several pictures of a Marine in WWII. It passed a black light test. Im not 100% its militaria but it is similar to size and weight to other squadron patches I have seen. Has anyone seen one before? Or have a possible ID? I have been searching for hours, found a lot of similar patches but not this one. Thanks as always!
