A short-lived 17 hp six-cylinder variant, the F-Type Oxford Six, was displayed for the first time as a four seated cabriolet at the November 1922 Olympia Motor Show.

[7] The all-steel body was made over the road at Cowley by W R Morris's joint venture with American Edward G Budd, Pressed Steel Company.

Standard fitments include: bumpers, a stoplight and dipping headlights pneumatically controlled from the steering wheel.

[9] In August 1930 a shorter chassis more expensive version was announced and named Morris Major Six, "A new light six-cylinder 15 hp model with a sparkling road performance".

[10] In September 1932, the gearbox gained a fourth speed and the engine grew to 2062 cc with the Q-series unit.

[11] Direction indicators, a set of three coloured lights on each side of the car visible from front and rear were fitted.

Controlled from a switch on the dashboard they permitted accurate indications of planned movements while the car's windows remain shut.

[11] In its road test The Times commented favourably on the direction indicators though it noted the lack of ashtrays.

New shaped coachwork incorporated improved running boards, a new pattern of brake lever, draught excluders over the slots for the pedals and gear lever and interior sun visors, twin rear and reversing lights, fog light, occasional table folded behind the front seats, new pattern armrests are place front and rear and a folding footrest provided for rear seat passengers.

[13] Reporting again in March 1934 The Times drew attention to the gearbox's free-wheel, quiet-third and synchromesh on the three top speeds.

[15] The engine's cooling system now had thermostatic control, mixture control was now thermostatic, direction indicators self-cancelling, the electric windscreen wiper was fitted with a blade for each side of the screen, Triplex safety glass fitted throughout.

[15] Barely nine months later these cars were superseded by members of the Morris Big Six series II range: Sixteen (later Eighteen) and Twenty-one (later Twenty-Five), announced 2 July 1935.
