Picked up a vintage Flight Ace officer's cap from a local antique shop. The shopkeeper didn't know anything about it, just that it was very old and probably from WW2. For $20 I felt like picking it up, but I don't know any details about it.
On the inside, the cream-colored fabric is covered in plastic:
Flight Ace logo (trade mark registered)
ALL WOOL
Except ornamentations
Ace Manufacturing co., Inc.
San Antonio, Texas
Size - 6 5/8"
On the outside:
The wool is green. The visor rim is black with no designs or ornaments. On the front, there is a copper-colored tin insignia of the eagle with arrow and olive branches on top of a separate circular piece. The same design is on two smaller versions the band on both sides of the hat.
No date or personal details. Any clues?
