Stevens had two plants by 1900. Their main plant was called the River Plant and they added the 'Hill Plant' in 1900. They also made machinist layout & measuring tools in one of the factories. The Stevens picture is from about 1903. I'm not sure where the automobiles were made. Savage was still using both plants in the '50's.
