1919
 

 
 
L.W.F. ENGINEERING CO.

June 1919 to December 1920.
     Employed by L.W.F. Engineering Co., as Aeronautical Mechanical Engineer to develop a 60 H.P. (Cato) air-cooled engine and light monoplane for this engine. This engine was stand tested for 27 hours and had 67 hours in the air powering the above monoplane designed for its installation, no changes in this engine were found necessary after my first design on the board.
