The early models featured a two-cylinder engine, while later ones had a water-cooled four-cylinder version. These models also had a friction transmission and shaft drive, a 9-foot (2.7 m) wheelbase, and a 3-foot-8-inch (1.12 m) track, costing $450.
Confusingly, another American company also offered a car called the Allen, also in 1913.
