This view from 1909 shows factory #12 with a sawtooth roof and a very long two story building with a roof vent. Both in the upper right corner. The later factory is where the Buick enamel plant #05 will be built in 1914 . Weston-Mott has also built their factory #2 behind Imperial Wheel Co. Buick’s future factory #34. The power plant has also been expanded. As you see they would just add detail to the previous drawing as the years went by.
