By 1913, the Fisher Body Company had the capacity to produce 100,000 cars per year. Customers included: Ford, Krit, Chalmers, Cadillac, Oldsmobile and Studebaker. Part of the reason for their success was the development of interchangeable wooden body parts that did not have to be hand-fitted. This required the design of new precision woodworking tools. In 1916, the Company became the Fisher Body Corporation. Its capacity was now 370,000 bodies per year.
