1933 SV Minor coachbuilt saloon

1933 side valve coachbuilt saloon

Introduced September 1st 1928 for the 1929 season. Initially in four seater Tourer and fabric bodied Saloon form. For the 1930 season a coachbuilt saloon version was available. All three types were listed for the 1931 season together with a one -year- only Semi-Sports Two Seater in fabric two-colour finish. The last of the overhead camshaft models can be included with the Minors as they continued to use the same chassis numbering series- these were the Family Eight Saloon and the Eight Sports Coupe on a long wheelbase chassis. Apart from the 1932 models, the Minor O.H.V. cars were fitted with a flat rectangular radiator with chromium plated finish for the 1930/31 season. Early models had a nickel-plated version with its surround integral with the radiator core and some of these sported an additional "MORRIS" motif on the honeycomb.

The first Morris Minor, fitted with a Wolsely designed single overhead camshaft four cylinder engine was introduced in 1929.  The lower cost side valve model was introduced in 1931. The ohc model was continued in production until the following year for the long wheelbase Family Eight saloon and Special coupe.

Contrary to popular opinion, the side valve-engined Morris Minor did not immediately supersede the O.H.V. version, for two years both types in one form or another, were being manufactured. The first of the side valve Minors arrived with the "100" two-seater in the early days of 1931. Four Seater and Fabric and coachbuilt saloon models quickly followed this. Understandably, many of the components used in the first of the S.V. Minors were common to its O.H.V. contemporary including gravity feed petrol tank. However in the cost cutting exercise the S.V. version had a paint finish radiator and had lost the bumpers, separate side lamps and the chromium plating on the bright parts. The chrome finish to the radiator shell and the windscreen surround was not absent for long, by the 1932 season it was back again on a new design of radiator with a shield shape badge. 1933 season saw the same radiator in use on 3 speed gearbox version of the Two Seater, by which year the other models had a radiator shell which had become longer and now overlapped the starting handle hole. The S.V. 5cwt van retained the rectangular radiator to the end. Major changes came with the 1934 model. Hydraulic brakes, synchromesh 4-speed gearbox, hydraulic shock absorbers, trafficators, smaller diameter wheels, and real leather upholstery on all models were some of the changes. The body design and in particular, the mudguards had taken on a more rounded appearance) these rounded mudguards being used previously on the 1933 season's long wheelbase models).
