136 pages, 39 black & white illustrations, size 5.5 x 8.5 inches. Originally published by Douglas Ltd UK, this book consists of two original factory maintenance manuals combined together in a single publication. The first 78-page section deals with the complete 1948-1951 range, including the Mark III, Mark IV, Mark V, 80 & 90 Plus models and the appropriate Sports, De Luxe & Competition derivatives. The second 56-page section is specific to the Dragonfly. As to be expected from a factory publication, it includes complete technical data, service and maintenance information and detailed instructions for the repair and overhaul of the major mechanical and electrical components. There is adequate detailed text and diagrams to assist in major refurbishing such as an engine rebuild or even a complete renovation. Obviously, the predominant focus of these manuals is the post-war models that were manufactured from 1948 until production ended in 1957 but much of the information will also be of interest to owners of the pre-war models. These factory manuals have been unavailable since Douglas was purchased by Westinghouse Brake & Signal in 1957 and they are becoming increasingly more difficult to find on the secondary market. We are pleased to be able to offer these reproductions as a service to all Douglas motorcycle enthusiasts worldwide.
