The firm advertised a bespoke car construction service, using proprietary parts to suit the taste and pocket of the customer. Woollan claimed ‘many years experience’ in motor manufacture and was held in high regard by Bernard Secretan a surgeon at the Royal Berkshire Hospital, who claimed to have made the first climb of Porlock Hill in a small car with a 7hp White and Poppe engined Swift in 1906. 1908 Secretan commissioned a 15.9hp White and Poppe engined car with initially a 2-seater Victoria body, which gave great satisfaction on overseas tours and also ran in stripped form at Brooklands. Despite such success there were few other takers, notwithstanding the Greek soubriquet of ‘Doru’ and the slogan ‘Swift and Silent as the Spear’. The firm developed instead their coachbuilding activities, particularly on the larger De Dion Bouton chassis, and later prospered as Caversham Motors Ltd.
