This book is a must-have for collectors and enthusiasts of militaria and World War II history. This 1941 edition of "Aircraft Identification friend or foe? Part one third impression 1941" is a guide to aircraft identification during the war. Printed by Temple Press during the war, the makers of the Aeroplane magazine at the time.
The condition is good for the age, given that these were paper pamphlets from 80 years ago.
I like the notion that these were given to children for them to go out and identify the aircraft during the blitz! In fact a lot of the collection have service numbers handwritten inside. This suggests they were used by the home guard and other servicemen during the period. These are getting harder to find and for the collector, they printed lots of variations to try to find.
