Personalized copy of the WWI dated machine gun manual. Front cover has the handwritten info "Co C 1st Tank Cadre A.E.F.". The word "cadre" is a guess as this is illegible. A.E.F. is "Allied Expedtionary Force". The cover shows superficial wear but is surprisingly strong and sharp. The pages inside are also crisp and clean and show 288 pages of text, photographs, charts and diagrams. Very nice, very early item relating to both WWI tanks and machine guns.
