Alter Motor Car Company

The car was made from component parts shipped to Plymouth by rail and then assembled at the Farmer Street factory.

The 1916 Alter model was described as "the classy look and finish of the higher priced cars", by the Plymouth Mail (local newspaper) on March 3, 1916.

The 1916 model had a 27 horsepower 4-cylinder engine, 12 US gallons (45 L; 10 imp gal) fuel tank under the cowl, with a wheelbase of 108 inches (2,700 mm).

In 1959, Mr. & Mrs Dale Blair from Upper Sandusky, Ohio, drove to Plymouth to see the factory where the vehicle was built.

Clarence Moore, a charter member of the Plymouth Historical Society eventually bought the car.
