It has been way too long since I have bought any militaria, but I have had a string of lucky finds lately. This isn't anything too special, but it was given to me, and you can't beat free! It's a service jacket for, I think, a flight mechanic in the 4th Air Force. I'm pretty sure this unit served the entire duration of the war in California.
I found the missing insignia inside the pocket! It looks like this guy's war service was nice and easy.
