Conversion. Pianos to airplane motors. Norwegian-born Edward Groe has been employed by a Chicago piano factory since 1909, regulating keys of electric organs. With the plant's conversion to the production of trainer-plane motors, this master mechanic has discarded instruments of peace, such as this electric organ, for weapons of war. He now regulates pneumatic motors of trainer planes which are used for instruction of America's flying forces. Gulbransen Company. Sourced from the Library of Congress.
