This book on Jaguar E-type originality is based on research spanning almost five decades, and Drs. Haddock and Mueller include here extensive new information from an exhaustive four-year examination of the Mueller collection of over fifty E-types. As such, the book is archaeological in nature, based more on observations of cars than on factory publications or other literature. The examination of principally un-restored cars, many partly or completely disassembled and still retaining their original configuration, permitted discovery of much detailed information not reported before. The large volume of data used in the compilation of this work permitted statistical analysis of production changes that would be impossible with a smaller data-set. It significantly advances the understanding of the original configuration of these remarkable cars
