US Air Force Belt Buckle from Siskiyou Buckle Co. This belt buckle measures 3 1/4" wide and is 2 1/2" high. The inscription on the back reads "In 1926 Congress created the Army Air Corps. Nineteen years later, in 1947, the United States Air Force was established as a seperate military branch. Today the U.S. Air Force is second to none." Our 1 1/2" leather belts would be the best fit for this belt buckle.
