A facsimile reproduction of the Great War pocket book. The contents provide an introduction to the then relatively new concept of the internal combustion engine with clear descriptions of the working parts, plus instruction on how to drive the tractors.

Very few original copies of this booklet still exist and this particular example has additional interest, as it was the property of ‘Sapper G E Poole’ ROTD, Longmoor. Sapper Poole added many pencilled notes and these have been reproduced at the back of the book, providing much in the way of additional information.
