Vintage original press photo, 9x7", b&w. Press release on reverse is titled "Wingless Autogiro is Latest". Photo was taken at Bolling Field, D.C. before a flight to Langley Field for testing by the U.S. Army. This model has no wings and is capable of 125 mph top speed, cruise at 100 mph. I am at a loss to identify the exact model but it has three main rotor blades, an engine cowl and up-swept horizontal stabilizer. Engine is running in the photo. Release is dated 12/17/1935. Very good.
