This might be a shot in the dark, but I was hoping someone could help possibly identify a squadron patch based on the outline of where it was once stitched. I recently acquired a Willis & Geiger M-422A jacket that is heavily worn, and on the chest are stitching holes from a patch. I don't know much about WWII/KW era USN/Marines jackets, but it seems like this is where a name tag could have been more commonly worn than another patch. The outline doesn't seem to match any WWII-era Navy patches I've seen in my research.
Either way, any help or direction would be greatly appreciated!
