Collection Item Summary:
The Liberty engine was America's most important contribution to aeronautical technology during World War I. Jesse G. Vincent of Packard and Elbert J. Hall of Hall-Scott co-designed it in mid-1917 for the U.S. government, which wanted a standard design in 4-, 6-, 8-, and 12-cylinder versions that could be quickly mass-produced to equip U.S. combat aircraft. Automakers Ford, Lincoln, Packard, Marmon, and Buick produced 20,748 Liberty 12s before the Armistice, which insured their widespread use into the 1920s and 1930s.
These tools were assigned to the 20th Aero Squadron, U.S. Army Air Service, and brought home from the war by Master Sergeant Chester Cy Martin. He used to them remove oil seals and bearings from Liberty engines. The tools were stored in his garage until 1998.
