Peter Snowden began to develop in his youth a strong interest in the history of vehicles and their operators covering the period from the 1930’s through to the 1960’s. Both he and his co-author, Cliff Marsh, have been involved with Steve Morris and his Heritage Fleet for many years, helping with restoration, driving the finished products, locating potential restoration projects and researching their history. Over the years they have seen well over 130 vehicles join the Heritage fleet.
