Overview
Alter Motor Car Company was an early American automobile manufacturer based in Plymouth, Michigan. It was organized on January 26, 1914, by Guy Hamilton, F. M. Woodward, and other local residents during the expansion of the United States automobile industry. The company constructed a factory on Farmer Street beginning in the spring of 1914 and used the facility to assemble cars from component parts shipped to Plymouth by rail. The automobile itself was designed by Clarence Alter of Manitowoc, Wisconsin. Alter's initial offering was a five-passenger touring car, followed later by a roadster. The company appears to have operated as a small regional manufacturer rather than as an integrated producer of every major vehicle component. Its business model depended on bringing parts into Plymouth and completing assembly at the Farmer Street plant, a structure that became a visible reminder of the town's early industrial activity. Production was significant for a local manufacturer but modest by the standards of the rapidly consolidating American automobile sector. At its peak, the factory employed approximately 100 people and produced as many as 25 vehicles per day. Across its operating period, the company produced more than 1,000 automobiles. The 1916 Alter represented the firm's later product development. Contemporary local reporting characterized the car as having the appearance and finish associated with more expensive automobiles. Its published specifications included a 27-horsepower four-cylinder engine, a 108-inch wheelbase, and a 12-U.S.-gallon fuel tank mounted beneath the cowl. The 1916 car was priced at $685. The company entered receivership in January 1917 and closed. No parent company, successor brand, or continuing automotive operation is identified in the available reference material. The former factory still stands near downtown Plymouth, across from the city's Cultural Center. It was restored in 2000 and was being used by the C. D. Sparling Co., a small manufacturing company, by October 2007. Alter cars are now primarily of historical and collector interest. Only one surviving example is identified in the reference material: car number 75, a 1915 Alter. In 1959, Dale and Mrs. Blair of Upper Sandusky, Ohio, drove the vehicle to Plymouth to visit the factory where it had been built. The car was later displayed at the Old Car Festival at Greenfield Village in Dearborn, Michigan, and was eventually acquired by Clarence Moore, a charter member of the Plymouth Historical Society. It is displayed at the Plymouth Historical Museum. Alter's significance therefore rests less on long-term commercial success than on its role in Plymouth's early manufacturing history and the preservation of one rare surviving automobile.
History
Alter Motor Car Company emerged in Plymouth, Michigan, during the formative period of the American automobile industry. The enterprise was organized on January 26, 1914, by Guy Hamilton, F. M. Woodward, and other local residents. Rather than representing a large established automaker, it was a local manufacturing initiative that sought to create an automobile business in Plymouth. Construction of its Farmer Street factory began in the spring of 1914. The company's cars were designed by Clarence Alter of Manitowoc, Wisconsin. Production involved the shipment of component parts to Plymouth by rail, followed by assembly at the Farmer Street plant. This arrangement reflects the production practices of many small early automobile manufacturers, which often combined outside-sourced parts with local assembly and brand-specific design or finishing. The first known model was a five-passenger touring car introduced for 1914. A roadster was added later. Alter reached a peak workforce of approximately 100 employees and reportedly produced up to 25 vehicles per day. Total production exceeded 1,000 cars between 1914 and 1916. The company's later 1916 model was promoted in local coverage for its appearance and finish. It used a 27-horsepower four-cylinder engine, a 108-inch wheelbase, and a 12-U.S.-gallon fuel tank located beneath the cowl. Its stated retail price was $685. The business did not survive the competitive and financial pressures of the early automobile market. In January 1917, it entered receivership and closed. The available historical account does not identify a successor automotive company, acquisition, or continuing Alter production. The factory remained standing on Farmer Street near downtown Plymouth. After restoration in 2000, the building was being used by the C. D. Sparling Co. by October 2007. The surviving historical record is reinforced by the preservation of one known Alter automobile. Car number 75, a 1915 model, was taken to Plymouth in 1959 by Dale and Mrs. Blair of Upper Sandusky, Ohio, who visited the former factory. It was later displayed at the Old Car Festival at Greenfield Village in Dearborn. Clarence Moore, identified as a charter member of the Plymouth Historical Society, eventually purchased the car. The vehicle is displayed at the Plymouth Historical Museum. Alter is consequently remembered as a brief but locally important participant in Michigan's early automobile manufacturing history.
