Only one Alter model is still known to exist, car No. 75, a 1915 model Alter. In 1959, Mr. & Mrs Dale Blair from
Upper Sandusky, Ohio, drove to Plymouth to see the factory where the vehicle was built. He later displayed the vehicle in the Old Car Festival at
Greenfield Village in
Dearborn, Michigan. Clarence Moore, a charter member of the Plymouth Historical Society eventually bought the car. It is now on display at the Plymouth Historical Museum. ==See also==
