Hello all, I found an Army Air Corp ring made of silver with the inscription "U. S. Army Air Corp" on the front and the initials WHG in the center. On one side it says "Nichols Field Nov, 37" and on the other side it says "Rizal P.I. Nov, 40". I looked up Nichols Field and found out it was in the Philippines during WW II. Does anyone know more about Nichols Field and its aircraft?
