Mr Munro's most useful publication is a very worthwhile addition, as it explains a lot of the technical aspects considered in the original design and subsequent evolution. It's also written in a hands on practical style and also contains more in the way of workshop data than a Haynes' Manual.
I know of two editions, 1955 and the second published in 1960, which covers the later swing arm framed models as well as the early Long strokes.
