they were faired into the wings, although the export type lamps could be specified. 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. Motor magazine tested a 328 cc Berkeley in 1957 and found it to have a top speed of and acceleration from 0- in 30.6 seconds. Fuel consumption of was recorded. The test car cost £574 on the home market including taxes of £152 (equivalent to £ today). The SE328 enjoyed considerable success and press exposure through their involvement with lightweight motor racing, and their famous drivers included Pat Moss who drove one in the 1958 Liège-Brescia-Liège rally for cars up to 500 cc. The Berkeley team – a works-supported entry of six cars including BBC commentator Robin Richards – led as far as Slovenia, but slow climbing in summer heat found their weakness and Pat ended up being towed back to Italy by another Berkeley. None of the Berkeleys finished the event. Sports and Twosome (SE492) In late 1957 a new derivative model was introduced, using a , Excelsior three-cylinder 492 cc engine with triple carburettors. This engine configuration was made possible by the vertically split crankcase of the Excelsior engine and modular crankshaft and barrels, which made adding a central cylinder relatively easy. A four speed gearbox was standardised. The top speed was now . Production ran from October 1957 to March 1959 with chassis numbered 1 to 666. From about October 1958, in order to coincide with the introduction of the 'Foursome' (see below), they were renamed the ‘Twosome’. Also at the 1958 Motor Show a Fixed Head (or Hardtop) was announced and displayed that had external as well as the usual internal door handles, but there are no records that this body style actually reached production. It is probable
