In the new Morris Oxford cars new ground has been broken with a range of speedy six cylinder luxury vehicles at a man who demands a car of outstanding performance and comfort coupled with moderate running expenses.

Among other refinements an air filter is embodied in the head, which, going a step farther, collects the fumes from the breather and thus removes any possibility of their vitiating the atmosphere of the car. After exhaustive preliminary tests the power unit has shown its capability of maintaining its tune over long periods without attention, and when such attention is necessary everything has been done in the matter of accessibility to render the task easy and well within the compass of the average owner driver's mechanical capabilities

Of paramount importance to the owner driver is the new finger tip control. Mounted on the Steering wheel, it gives instant access to the lighting, ignition control and slow running setting for the throttle. With the Bishop earn type steering gear, finger light in its action, and Lockheed hydraulic four wheel brakes, the driver is assured of decelerating powers in keeping with the brisk acceleration of the power unit .

And, on the score of appearance, these cars can hold their own in any company the stamp of the thoroughbred is on them al. lines are set off in no small degree by the broad doors, which facilitate ingress and egress, and the wire wheels which are fitted as standard throughout the range.

General
The design consists basically of a six cylinder water cooled engine with totally enclosed clutch and three speed gearbox in unit construction. This power unit is mounted in an all straight frame of unique design, to which are attached, by long supple semi-elliptic springs fore and aft, axles providing a wheelbase of 9 ft. 6 in., and a track of 4 ft. 8 in.

Engine
The six-cylinder engine has a bore of 63.5 mm., and a Stroke of I02 mm., giving a cubic capacity of 1938 c.c, (juSt under two litres), with a Treasury rating of 14.9 h,p" and a tax of £15. The cylinders are caSt en bloc with the skirt of the crankcase, which is extended well below the crankshaft centre and reinforced with liberal internal webs at the main bearing locations, producing a deep girder Structure of great Strength and rigidity, The crankshaft is of the four-bearing type, having the maximum possible dimensions. Each individual crankshaft is balanced to fine limits, both Statically and dynamically, by the Olsen method, The main bearings are of diecast white metal accurately machined to such close limits as to render hand fitting unnecessary and interchangeability certain. The steel connecting rods are equipped with full ring type white metal big end bearings die cast in position, and are individually balanced to a high degree of accuracy. The aluminium piStons are of the three ring type, the lower ring being of the oil seal pattern. They, in turn, are individually balanced, and the complete assembly of rod and piston is equalised in weight to within 0.2 ounces. side-by-side valves are fitted and operate in conjunaion with an "L" type detachable head of a patented anti-detonating design, whose combuStion spaces are completely machined to ensure equality of compression and reduction of carbon deposits to the greateSt possible extent. The valves are operated by tappets and a hollow camshaft of large diameter running in three generous bearings, The camshaft is driven by a duplex roller chain from the crankshaft. The tappet guides are in two units which can be completely removed without interfering with any other component, and the tappets are spring loaded to ensure silence of operation, Induction pipe and exhauSt manifold are caSt integral and provided with adequate hot spots, the induction pipe feeding into short independent valve ports. An intereSting feature of the induction syStem is the combined preheating cover and air cleaner which also collects all fumes from the crankcase breather.

Lubrication
A spur gear pump mounted on the oil sump and driven from the camshaft supplies oil for a full forced feed oiling circuit. The oil leaving the pump passes through an external filter of the" edge filtration" type before entering the circuit. The oil filter is automatically cleaned every time the clutch pedal is depressed. An additional filter of conventional design surrounds the pump intake,

Cooling System
A centrifugal pump driven from the dynamo shaft circulates the cooling water from the base of the cylinder jackets upwards, from whence it passes out of the cylinder head through three carefully positioned ports which ensure even temperature distribution. The cooling water is automatically maintained at the most effective temperature by calorstat operated radiator shutters.

Electrical Equipment
The distributor for the coil and battery ignition runs at one-half engine speed. where it is readily accessible. The dynamo is situated alongside the engine detachable. The gear type Starter motor is located at the side of the gearbox, and has its pinion supported on either side. Five lamps are provided, including dipping headlights, sidelights and stoplight. All switches, together with the ignition and slow-running adjustment for the throttle, and horn push, are mounted in the centre of the steering wheel, thus providing finger tip control. All elellrical units arc supplied by Messrs. Joseph Lucas Ltd.

Carburation
An S.U. carburetter of the automatic piston type, with adequate control over mixture Strength, operated from the Steering column, supplies the working mixture.

Transmission
A clutch of the multi-plate type having cork inserts in light alloy plates, and automatically fed with oil, ensures sweetness of action. All gears are of case hardened nickel chrome Steel. The primary and main shafts are mounted on generous ball bearings, while the Sturdy one-piece layshaft rotates on bronze bearings of more than ample dimensions. The splines of the mainshaft are ground all over. A tubular propeller shaft transmitting the drive to the spiral bevel final drive gears in the rear axle is totally enclosed in a torque tube and provided with a single universal joint (also totally enclosed) of the ring type.

Four Wheel Brakes
Fully compensated four-wheel brakes of the Lockheed hydraulic type, operating within 14 in. drums, ensure the maximum of braking efficiency. Their efficiency is maintained under all circumstances, since lost motion or loss of leverage is eliminated. The hand brake operates on the rear wheels through cable mechanism which can be adjusted from the driving seat while the car is in motion, if necessary.

Petrol Tank
The petrol tank is mounted at the rear of the chassis and has a capacity of twelve gallons. It is fitted with an efficient pebble guard, and its contents are indicated to the driver by an electrically operated dial gauge on the instrument panel.

Steering
The Steering gear is of the Bishop earn type, safe, extremely light in operation and giving a fine sense of controllability.

Main Fraime
Parallel in plan and perfeCtly Straight in elevation except for a rise over the rear axle, the frame is provided with Sturdy cross members which extend well beyond the deep sectioned side members and carry both the body and the running-boards. The top of the frame is but 18 inches from the ground when loaded, and this low position has been made possible by shackling the front springs at their forward end and mounting them outside the frame. Long semi-elliptic springs front and rear, controlled by hydraulic shock absorbers of the single-aCting progressive type, provide superb suspension. The springs are enclosed in leather gaiters to proteCt them againSt road dirt.

Wheels and Tyres
Detachable wire wheels fitted with Dunlop reinforced cord balloon tyres are standard equipment. They are attached to the hub by five Studs with plated domed nuts and spring washers.

Tool Kit
A full kit of tools is provided with every car. These are housed in a substantial weatherproof toolbox immediately accessible
