4/4 revived after a five-year lapse, with the latest (1954) Plus-Four styling. 36bhp 100E Ford engine, and hydraulic brakes. 40bhp Aquaplane-head engine available from '57, wider body on very last SIIs. Debits are three speeds only and a rather nasty push-pull gearshift beneath the dash. Later ohv models preferred.
