This is the classic booklet from the legendary model engineering company established by Percival Marshall in the early 1900s. It details how to machine and assemble the Stuart No. 10 Engine model kit, as an operating live steam model. Amazon lists originals of this booklet as high as $800.00 for some insane reason.
Edgar T. Westbury (1896-1970) wrote nearly 1,500 articles for the English magazine Model Engineer. The articles appeared under his own name, and also under the pen names of 'Artificer', 'Ned', 'Kinemette' and Exactus. He served in the Royal Navy during the First World War, then served as an an instructor in the Royal Air Force until the late 1920s. He designed and built the "Atom Minor" model aeroplane engine of 1926, which established a model flight endurance record. During World War Two, Westbury designed and developed a number of small gasoline fueled field generators for use by the armed forces.
