The Partridge-Keller Bi-Plane aka “Looper” was built in 1914 especially for Katherine Stinson for her exhibition flights in North American and the Orient.
At first the two place open cockpit biplane was powered by an 80hp Gnôme rotary and had an uncovered fuselage. Later, power was changed to an 80hp Smith 6-cylinder radial and the fuselage covered with fabric.
