This 1899 Knox was custom built for Everett H. Barney, Springfield philanthropist and co-founder of the Barney & Berry skate company. It has a one-cylinder, air-cooled engine and is a three-wheeler. Steering is done by tiller, and the brake is applied directly onto the drive shaft. A crank applied on the side would start the vehicle, and once running, you could expect to travel no faster than thirty miles per hour. The gas tank, filled, would hold six gallons. Purchase price at the time, depending on finishes, ran between $750 - $1,200.
