Can someone identify this biplane? It was taken in late 1920 or early 1921 when my grandfather was barnstorming in Arkansas. My grandmother and aunts are also in the photos. Additionally, can someone identify where in Arkansas this Hickman Air_____ was located?
It looks like a Curtiss Oriole. Note the smooth and rounded fuselage and how it comes to a rounded point under the tail. Additionally, note the engine manifold covers and some sort of extended "stack" from the rear of the engine.
