IT is the standard early 4 pocket issue. It appears to have been reissued twice.
The First Airforce was a state side outfit.
During the war its primary duty was to defend the eastern seaboard till 1943, then relieved and became a traing outfit that turned out 350 combat units that comprised over 7,000 pilots and 80,000 enlisted men. The shoulder patch was approved January 18 1944.
Hope this helps buddy.
Pictures always make the difference.
