MORRIS ISIS 1930 to 1935
 

 

The Isis-Six (or plain "Isis" as it was later called), introduced to the trade in July 1929 for the 1930 season, was very American in appearance and even today's trend for bright colours could hardly match these first Isis models.

Although the mudguards followed the normal Morris practice of being finished in stove enamel Black, the wheels and brake drums created something of a precedent (if the very early Bullnose models are ignored) by the application of greens, Blues, and even Ivory. By 1931 Season the paint shop had sobered up somewhat.

All-steel bodies were used for the first two seasons but by 1932 the coachbuilt body was again used. All Isis models were fitted with Lockheed hydraulic brakes, rear mounted petrol tank, twin-bar bumpers, and a central accelerator pedal.
