Miles Spickler built his first midget racecar in 1936 for his brother, Burton, and drove to six main event victories in 1937. After serving in World War II, he returned to Colorado and built a number of midgets that he drove and had others drive, as well. Roy Bowe drove one of his cars to the Rocky Mountain Midget Racing Association championship in 1949. He became the chief mechanic on the Springfield Welding Special that won the National Championship in 1952. He worked for several Indy Car owners before leaving racing to join Ford Motors.
