In 1930 Mrs. Gwenda Stewart broke the One Hour World Record at the banked race track at Monthléry, south of Paris, at a speed of over 100 m.p.h. She was later to achieve 117 m.p.h. in a single-seater Morgan on the long straight at Arpajon nearby. 1931 brought a new transmission system with a three speed and reverse gearbox, a single chain and detachable wheels. This arrangement was eventually used on all models, with engines now supplied by Matchless, the high performance machine (a development of the Super Aero) being known as the Super Sports (Photo 28). Morgans remained at the forefront of competitive motoring and even Harry’s daughters were seen at Donnington at an A.C.U. rally.
