MORRIS MAJOR 1931 to 1933

The Morris Major as first introduced for the 1931 season was almost a Morris Cowley in 6 cylinder disguise, having a common wheelbase and many interchangable components.For the following two years a Major model was also listed, but everyone following the normal rule of searching for spares on a near-year model should be warned that the 1931 model and those of the two following years differed so much it is surprising that the model title and chassis series was shared.
