Henderson Model Z and Z-2

The Henderson Model Z of 1919 was the next Henderson four built at the Excelsior works in Chicago, and it still used the Detroit designs. Its in-line four-cylinder engine had a capacity of 70 cubic inches (1,147 cc) and developed 14.2 horsepower. The Z 2 was the electric version, fitted with a General Electric generator. The model wore a new Henderson logo that included the red Excelsior X, and 1919 also brought a twin rear brake, with an internal expanding band and an external contracting band acting on the same rear drum. The internal brake was connected to the long hand lever that had replaced the clutch function, so that the lever served as an emergency brake with detents for adjusting manual braking pressure. A four-cylinder, 14 horsepower machine in khaki green, a colour scheme Henderson used at the time, probably carried C K Shepherd, the first Englishman to ride coast to coast across the United States, in 1919, although he never named the make.
