Colby (United States)

Colby Motor Company was an American automobile manufacturer based in Mason City, Iowa, that operated from 1911 to 1914. The company was founded by William Colby, who had previously partnered with David W. Henry, known for producing the Henry car in Muskegon, Michigan. Colby Motor Company introduced its first model, featuring a conventional design powered by a 40-horsepower four-cylinder Excelsior engine, and successfully completed 100 units by the spring of 1911.

In August 1911, the company launched the 1912 Model L, which was equipped with a smaller 30-horsepower engine and featured underslung frames. This model was available in various body styles, including tourer and roadster, while the original 40-horsepower model continued to be produced. In December 1911, Colby Motor Company merged with the National Cooperative Farm Machinery Company of Davenport, Iowa. Following the merger, William Colby remained as president, while David W. Henry was let go. The merger initially appeared beneficial, as 1912 marked the company's most productive year, with a total of 203 cars manufactured.

By 1913, Colby vehicles were equipped with four- and six-cylinder Continental engines. However, in October of that year, the company was sold again, and William Colby exited the business. The new owners, Standard Motor Company, had ambitious plans to establish a $3 million factory in Minneapolis, but these plans did not materialize, and production dwindled in 1914. Reports indicated that the company was losing approximately $1,000 per day and was sustained only by financial contributions from a wealthy widow. When her son ceased these donations, Colby Motor Company declared bankruptcy. In total, it is estimated that around 550 cars were produced during the company's brief existence.
