The WftW Compendium series is a new addition to the ‘Wireless for the Warrior’ range of books covering the technical history of British Army communication equipment. The Compendium series is principally intended as a practical guide and reference source to vintage military signal communication equipment. It is particularly valuable to anyone with an interest, professionally or otherwise, in this subject, requiring an elementary but complete quick reference and recognition handbook. Containing condensed data summaries, liberally illustrated with photos and drawings, explanatory captions and short descriptions of the main ancillaries, its pocket size format and laminated soft cover makes it an ideal reference and reliable companion for events such as auctions and radio rallies, or just for browsing at leisure.Wireless for the Warrior (WftW) Compendium 1 ‘Spark to Larkspur’ (Wireless Sets 1910-1948) and Compendium 2 ‘Spark to Larkspur’ (Special Sets, Receivers and Larkspur), the first books in this series, provide basic technical data on radio sets, radio stations and associated or related equipment used by the British Army during the period 1910 to the late 1950s. These two books are based on a massive amount of hitherto unpublished source material, including manuscripts from the projected, but never produced, WftW Volumes 'World War 1-the Spark and After', 'Interwar Wireless' and 'Larkspur', and condensed but reworked material from the WftW Volumes 1-3.
