Yes indeed. And my faltering memory banks were confusing the puzzle car with the later single-sleeve-valvers. I was told by a former Arrol-Johnston agent (Unity Garage, in Altricham, Cheshire) that back in 1913, "Bombardier" Billy Wells owned an Arrol-Johnston Electric car. This was most likely a license-built Detroit Electric.
Wells, the renowned heavyweight boxer, sealed his immortality by becoming the mascot of The Rank film studios. He was the guy who struck the massive "gong" at the beginning of their films.
