The Liberty L-8 (also known as the Packard 1A-1100) was a prototype of the Liberty L-12 engine designed by Jesse Vincent and Elbert Hall. Fifteen L-8 prototypes were manufactured by several companies including Buick, Ford, Lincoln, Marmon, and Packard in 1917.[1] [2] The first of those built now resides in the National Air and Space Museum in Washington, D.C., while fifteenth L-8 (the only running example) powers Liberty the Second housed by the Conneaut Lake Historical Society in Conneaut Lake, PA.[3] Another L-8 is stored at the National Museum of the U.S. Air Force in Dayton, OH.[4]
