This 1921 Cunningham Roadster is a model V-4 but it was powered by a V-8.

Built for Air Force Major M. K. Lee on a 142 inch wheelbase chassis. This car had shatter-proof glass, a 50-gallon gas tank, an oil supply good for 5,000 miles, a Kellogg one-shot lubricator (pressing the foot pedal lubricated all chassis points) and triple windshield wipers. The dashboard contained a combination of 42 instruments, switches, and miscellaneous gadgets including many normally found only in aircraft cockpits. Among them were a tachometer, radio switch, fuel gauge, altimeter, voltmeter, ammeter, oil gauge, light switch, ignition switch, an imported French speedometer engraved with Major Lee's name, two motometers, aviator's compass, air speed indicator, etc. There were 8 lights beamed forward, 2 headlights, 2 "ditch" lights, 2 inside adjustable spotlights, and 2 sidelights. There were also parking, dome, dash and running board lights.

In this picture, it has a 1925 Washington, DC license plate but is sitting in front of the Cunningham factory on Canal St.
