1910 Knox Type O 5-Passenger Touring
Progressive engineering distinguished this Massachusetts-built luxury automobile during the final years of America’s pioneering automotive era.
Knox had evolved from its famous air-cooled “porcupine” engines with cooling spikes to sophisticated water-cooled powerplants featuring overhead valves for both intake and exhaust (a remarkably advanced configuration for 1910).
The Type O’s 373-cubic-inch four-cylinder engine produced 45 horsepower from its oversquare design with a 5-inch bore and 4¾-inch stroke. This powerplant was paired with a finely engineered aluminum-cased transmission and an unusually smooth oil-bathed clutch, representing cutting-edge technology for the period. A modern shaft-drive system replaced the earlier chain-drive arrangement.
Originally priced at $3,250 when the average annual income was about $575, these substantial touring cars appealed to wealthy buyers seeking both luxury and reliability.
Knox automobile production ended in 1914, making survivors from this respected Springfield manufacturer exceptionally rare and highly sought after by collectors of American brass-era automobiles.
