- Splitdorf Dixie Magneto, 1915-1925 - Magnetos served as simple, reliable ignition systems for internal combustion engines in early automobiles, motorcycles, and airplanes. Modern ignition magnetos are still found in lawn mowers and chainsaws, and aircraft use magnetos as an independent electrical system. Auto manufacturers, however, found other methods to keep engines turning.

- Bosch Type ARN Magneto, Used by Orville Wright at Fort Myer, Virginia, 1909 - Orville Wright used this magneto, which generated spark for his airplane's engine, during demonstration flights for the U.S. Army at Fort Myer, Virginia, in July 1909. Fort Myer represented tragedy and triumph. Orville was seriously injured, and passenger Thomas Selfridge was killed, during initial demonstrations there in September 1908. Ten months later, Orville returned and completed the demo flights successfully.

- Drive Adapter Accessory for Sun Motor Tester, 1945-1955 - A motor tester combined several different engine diagnostic instruments into a single unit. It was used to identify problems with ignition and electrical systems, vacuum pressure, engine speed (crankshaft revolutions per minute), and emissions. Racing driver Bobby Unser used this Sun motor tester and its accessories at the Unser garage in Albuquerque, New Mexico, early in his career.

- Equipment for Testing Magnetos in the Ford Motor Company Highland Park Plant, circa 1913 - The Ford Model T's magneto generated electricity to produce the spark that ignited the fuel-air mixture in its engine cylinders. The T's magneto was built into its flywheel rather than as a separate unit driven by a belt or chain from the engine. The design typified the clever, compact engineering found throughout the Model T.

- "The Bosch Ford Attachments," circa 1914 - Bosch's "Red Devil," created in the early 1900s to promote the company's ignition components, was based on racer Camille Jenatzy. The red-haired Belgian driver was noted for his flamboyant appearance including a pointed beard, flowing duster, and goggles pushed atop his head. Jenatzy's daring driving won the 1903 Gordon Bennett Cup race -- with a Bosch ignition system in his car.
