Original WWII Army Air Corps Flying Tigers Uniform Tunic Jacket

This is an original vintage WWII Army uniform tunic jacket. I found two small moth holes. One near the right pocket (Picture 7), another near the back hem. (Picture 8). This jacket has no identifying tags, it is very small so please take note of my measurements. It is 20" across the chest from armpit to armpit. The shoulder area at the back of the jacket is 16" across from arm seam to arm seam. The sleeves re 25 1/2" long from the shoulder seam to the end of the cuff.
