The 1910 Stanley Model 70 is a 20 horsepower steam car with a 23 inch boiler and H-block engine configuration. The pump box is located under the driver's feet, below the floorboards. It contains three pumps: One pumps water into the boiler; another pumps kerosene into the fuel tank at 100 pounds per square inch; and a third pumps steam cylinder oil into the steam line using a tiny, 1/8 inch piston.
The five-passenger touring body is constructed of ash wood, the wheel spokes of hickory, and the headlights and instruments of brass, popular for its malleability and corrosion resistance.
In 1899 Freelan Stanley and his wife Flora climbed to the top of New Hampshire's Mount Washington in their Stanley, the first time any automobile had done so. And in 1906 Fred Marriot set the land-speed record for the fastest mile ever driven in an automobile at nearly 128 miles per hour.The feat was accomplished in the now-famous Stanley Rocket.
