Edmund Nankivell has owned Jupiters since 1967. He bought an interesting special-bodied example in 1969, which was restored and on the road by 1971. This aroused his curiosity about Jowett and Jupiters: their successes in national and international competition, and the Jowett company's triumphs, trials and tribulations. This led him into intensive research: interviews and correspondence with competition drivers, Factory personnel up to a very senior level, and several others associated with the Jowett company and its post-war models, and his research has led to books and magazine articles. He has detailed documentation on every Jupiter and produces detailed registers for the Jupiter club, as well as creating and running the Jowett Jupiter website.
