- We Hand You a Hint: The Hemco Twin-Lite is Made of Condensite, circa 1915 - Chemically synthetic plastics were developed in the early 1900s to replace shellac and hard rubber -- naturally derived substances increasingly in demand for various industrial applications. The Condensite Company of America formed in 1910 to sell a new material first developed at Thomas Edison's West Orange laboratory for phonograph records. Durable and nonconductive, Condensite was well suited for electrical products.

- Drawing, "Fuel PUmp Assembly," Ford GP, April 9, 1937 - The Ford Motor Company created over a million parts drawings from 1903 to 1957. Many of these drawings specify engineering requirements for the components of Ford-made vehicles--including automobiles, trucks, tractors, military vehicles and Tri-motor airplanes. Others document assembly components, stages of casting and forging, or experimental designs. Beginning in the 1940s, Ford transferred the drawings to microfilm.

- Glow Plug, 1975-1985 - Diesel engines use highly compressed hot air to ignite fuel. In cold weather, this compression process may not heat the air sufficiently to ignite the fuel and start the engine. A glow plug helps raise the combustion chamber's air temperature. The glow plug seen here is from a 1980s Mercedes.

- 10 Millionth Catalytic Converter Built by AC Spark Plug Division of General Motors, 1976 - Fighting air pollution required changes in car design and gasoline. General Motors developed the first practical catalytic converter, which turned automobile exhaust into less-harmful gases, in response to the Clean Air Act of 1970. Beginning in 1975, federal regulations required catalytic converters and phasing-out of leaded gasoline, which interfered with the converters' operation.
