General History

In 1906, the Stanleys developed their strongest power plant ever, using a 4½-inch x 6½-inch engine and a 30-inch-diameter boiler. That same year, this power plant drove their streamlined racer to a world land speed record of 127.66 MPH. By 1907, the same power plant, with a somewhat smaller boiler, was installed in a very light three-passenger vehicle, creating one of the very first muscle cars. The catalog termed it a “semi-racer,” and only 26 were built.

There is a drawing of the side profile of the 1907 Stanley Semi-Racer Model K. Above the car it says "Stanley Steam Car" and below it says "Model K. Semi-Racer, seating two, with rumble seat added. 26-inch boiler and burner in front 4 1/2 x 6 1/2 inch engine. 30 horse-power." Underneath that in smaller font it reads "Divided seat. Throttle and by-pass lever sub-imposed on steering wheel. Gasolene capacity (tank at extreme rear), 125 to 150 miles (13 gallons). Water capacity, 40 to 50 miles (36 gallons). 36 x 3 1/2 inch tires. Wheel base, 108 inches; track, 54. Full eliptical springs. Oil lamps, gague lamp and horn. Price net cash, F. O. B. Newton." To the right of this text in a big font it reads "$1,800"

Our Model’s History

The 1907 Stanley Semi-Racer Model K in our collection is not the first one to be owned by the Marshalls. In July 1910, T. Clarence Marshall bought a used Model K and owned it for three years. That vehicle was later broken up and the parts were thrown in the back corner of a machine shop in Avondale, Pennsylvania. In 1945, Hyde Ballard, a personal friend and an active member of the Antique Automobile Club of America, gathered up what he could find and used many of the original parts to rebuild the car. Tom Marshall then acquired and restored the Model K in 1986, and it has been in our collection to this day.
