Two photograph albums documenting the Service Conveyor company in Detroit, Michigan. Credited photographers include Manning Bros. Commercial Photographers, Stinson, and Robert E. Stoffer. Volume A contains views of machinery, the shop floor, transport vehicles, men presumably associated with the company, various parts of the factory, and images of the company's product in action at the Studebaker plant in South Bend, Indiana. Also of interest is an image of a possible schematic for a conveyor system in an aircraft plant as well as several pieces of advertising ephemera and a letter from the Chas A. Strelinger Company to C. M. Drake dated May 5 1948 regarding "the one and only continuous chain system" at Fisher Brody and the "roller turn" developed by George Maurath. Volume B contains five paper headings relating to "sections" of the album (what sections pertain to is unclear) and five photographs of machinery within the factory including two labeled "FoMoCo Valve Handlings."
