I am posting on behalf of our Collecting Semper Fi Brother - AZPHIL tonight as he is having computer issues. He snapped a couple pictures today at a building he is stationed at this week. He wants data or wondering if anybody has seen this type of USAAF enlisted collar device. MSgt Uniform. They are normally solid and not cut out like this one. Any info would be great. Please opine when you can on the uniform pictures. The 3rd picture is to make sure he is paying close attention when looking at SS Items.
