In book form the contents of this CD would be the final volume in Bob Whitehead’s history of Garretts and their products. Almost certainly correctly, Bob felt that a 536 page book on this aspect of Garretts products was not commercially viable, so has made the book layouts available here on CD. What you have are a total of 13 chapters covering portables, hoists & winders, semi-stationaries, uniflow engines, straw-burning etc., etc., all fully illustrated, which can either be viewed on your computer, or printed out. Usual Whitehead quality of research and text, this really is a very cheap way to acquire a lot of information!
