A very user friendlystraightforward and encouraging book in which the author guides the reader through the techniques necessary for loco building, covering the two disciplines of kit- and scratch-building.As he doesn't feel there has been any appreciable difference in his approach to modelling in 4mm to 7mm and 10mm scales, the book should prove usefull to everyone, but 7mm is the focus through the pages.A main theme of the book is that Geoff covers the building of two models of a sgnature class, one kit-built and one from scratch in order that the different proceedures can be seen in direct comparison.
