Auto conversion to airplane engines. With one hundred percent conversion of this automobile factory to production of airplane engines, the gigantic task of remodelling old machinery, removal of old and installation of new equipment, and extensive rebuilding of the plant itself was formidable--but speedy. Under terms of its contract, production was not scheduled until October, but Herulean efforts of management and labor reduced this to early spring of this year. Carloads of scrap material torn out of the plant are shown here at a siding back of the factory. Chevrolet, Buffalo, New York
