"The Vital Spark - the development of aero-engine sparking plugs" by Keith Gough, published by The Rolls-Royce Heritage Trust

Not to be confused with the Clyde steamer of the 'Para Handy Tales', but instead this is the comprehensive technical story of the development of high performance, high reliability spark plugs for use in aero engines, dating from the early days of aero piston engines up to the advent of the jet engine. The author was an expert in the field having joined KLG in the 1950s. A must for all aero engine technical buffs who want to know the story on a frequently taken for granted, but vital, component in an engine.

This book was first published in 1991 (59 pages, 62 b/w photographs/illustrations ) by The Rolls-Royce Heritage Trust as part of the Technical Series
