Early cars from Jan 1957 to about chassis number 476 in June 1957 still used a column gear change. During their production run a Deluxe model was offered which was bodily the same but featured polished wheel trims and spinners, tachometer and twin carburettors. The chassis plate was similar to the Anzani type on the early cars but was later changed to a printed type fitted to the bulkhead above the brake master cylinder. The printed type chassis plate had type ‘SE328’ printed on it. Most of these cars had the three-speed gearbox similar to the Anzani except for the mounting flanges. All of the cars had the sloping leading edges to the doors.
