The Roamer Duesenburg, 1921 Daytona Beach speed record holder

Roamer automobiles were built from 1919 to 1926 in Kalamazoo, Michigan. They were 'assembled' automobiles, which means the components were purchased from automotive supplier companies and then assembled at Roamer's plant.

This was typical of many low volume automobile companies that did not have the resources to design and build their own parts. Roamers were known as sporty automobiles and their designs reflected the look of the Roaring 20's. Two models were produced http://www.conceptcarz.com/vehicle/z15634/Roamer-Roadster.aspx

The Roamer was marketed from its inception as "America’s Smartest Car." It was also successful in many early racing events. After a Roamer with a Rochester-Duesenberg engine set six records for one kilometer, one-, two- three-, four- and five-mile sprints at Daytona Beach in 1921, the advertisements crowed, "America’s Smartest Car Makes America’s Fastest Mile."
