The story
The Falcon-Knight was intended to fit in price between the Willys Whippet and larger Willys Knight ranges and was priced $1250, $100 less than the Willys Knight 70A Roadster. It was powered by a six cylinder Knight sleeve valve engine. Except for the engine, much of the car is actually the same as the Model 93A Whippet with many parts being interchangeable.
In January 1928, a new model 12 was announced with mainly cosmetic changes, and the last cars were made in March 1929 after which the plant made truck parts.
