The 1920 Anderson Six Convertible Roadster is remarkably well preserved and is the only known surviving example of one of the marque’s most innovative body types. The Convertible Roadster design is another of the notable innovations of the Anderson company and John Gary Anderson. Based on a US Patent granted in 1916, the body style allowed for a car to quickly “convert” from a sleek roadster to a five-passenger touring car, similar to the commonplace hide away rumble seats that were to appear in roadster and coupe designs later on. The Convertible Roadster was first offered for the 1919 model year and remained in the lineup until 1922.

This particular example, car number 34142, has never undergone a complete restoration and represents the original imprint of its manufacturer and the craftsmen who built it. Furthermore, its original, numbers matching, aluminum block, six-cylinder Continental 7-R engine and running gear operate as they did when the car drove off of the assembly line in South Carolina circa 1920.

Ironically, a lumberjack supply salesman in Portland, OR, is believed to be the first owner of this notable Southern car. The “accessory” tow hitch is thought to have been used by the original owner to pull a camper between logging camps as he peddled his wares. After its use in the Pacific Northwest, the car cycled through a number of sympathetic owners and collectors on the West Coast before Mr. Ianaurio was able to acquire the Convertible Roadster and bring it back to its home state in 1989.
