3/4 (TQ) midgets at the Petersen
The Richard Varner Gallery of the Petersen Automotive Museum has a current exhibition through 2018 entitled "Harley vs. Indian." The author really isn't a motorcycle guy, but the exhibit featured a pair of early 3/4 (TQ) midgets, powered by (as you might have guessed) Harley Davidson and Indian engines. The Harley powered car was emblazoned "Half a Harley" so its safe to assume that the Indian TQ midget was also a single-cylinder power plant adapted from a motorcycle.
