Morris Minor - A Brief History

Following from the success of the Series MM the Morris Minor went through numerous changes throughout its production life. The brief history below details some of the changes which occurred in each version of the Minor.

Car Model	Chassis Numbers	Years
Series II	(c) 160001 to 448714	August 1952 to September 1956
803cc A Series Engine
The Series II Morris Minor saw some key changes in the Morris Minor's history. Following the merger of Austin & Morris companies to form BMC the Minor was fitted with Austin's 'A Series', 803cc engine, replacing Morris's side valve engine. Other notable changes that took place during the Series II production include: fitting of A type rear axle; a revised dashboard with a central speedo and glove boxes either side; slatted grille with repositioned side lights; Deluxe models with leather faced seats, heaters, passenger sunvisor & overriders were also offered. The Series II also saw the introduction of new body styles; the 4 door Saloon, Traveller, along with the light commercial models - quarter ton Van & Pick up.
Series III	(c) 448801 to 990289	October 1956 to September 1962
948cc A Series Engine
The introduction of the Minor 1000 brought with it more improvements. The engine's capacity was increased to 948cc giving improved performance desired by many motoring journalists of the time; the split windscreen was replaced with a larger single piece, curved screen; the rear screen was also enlarged; a dished & wire spoked steering wheel was introduced; horn & trafficator controls were moved to a stalk switch on the steering column, latterly indicators were introduced with an integrated warning lamp on the end of the stalk, the horn was repositioned to the steering wheel; larger side lights were also added during production.
Series V	(c) 990290 to 1294082	September 1962 to April 1971
Late 1000
1098cc A Series Engine
The Minor 1000 was further updated with the 1098cc A Series engine, again giving more power & torque, fitted with a new design of air filter; the body remained largely unchanged from the 948cc model but the wipers now operated in tandem and were fitted with longer arms & blades; external changes included the fitting of combined side/indicator lamp units; the fascia was changed to include the chrome & alloy surround for the speedo and a glove box lid added to passenger's side with driver's side open; two-spoke safety steering wheel introduced; redesigned interior trim with heat-formed vinyl panels.
