This is a Workshop Guide for the small chassis Rolls-Royce. The book is intended to help the average owner gain a deeper understanding of the car. It includes 100 workshop photographs & illustrations, designed to help the owner maintain their own car in first class mechanical condition. Included is data and servicing information, updated to take advantage of the availability of modern high tech oils and materials. Plus many 'Useful Contacts' and sources of supply. At the same time, the book is also the fascinating story of an early 20/25 Thrupp & Maberly tourer. It chronicles the Derby birth, the social history, the mechanical puzzles and the solutions found, in bringing this 1929 20/25 back to top class condition. "The quality will remain, long after the price is forgotten", Henry Royce once sagely observed. How right he was.
