Production. Pratt and Whitney airplane engines. They'll soon be adding to the power of our mighty American air forces. Rough forgings for the master piston rods of Pratt and Whitney motors are ready for the fine machining that will transform them into the precision-made engine parts that account largely for the excellences of American fighting aircraft. Pratt and Whitney Aircraft. Sourced from the Library of Congress.
