The British Aircraft Specifications File is a comprehensive reference work detailing British military and commercial aircraft specifications from 1920 to 1949. Authored by K.J. Meekoms and E.B. Morgan, the book was published in 1994 by Air-Britain Historians Ltd. It provides an in-depth look at the specifications for over 850 aircraft, including both prototypes and production models, and is illustrated with 250 photographs and technical drawings. Condition: Pages are clean with no visible markings or annotations, except for some writing on the very first page. The spine shows very light creasing along either side but remains structurally sound. Top edge of the text block displays light yellow/brown spotting (likely foxing) when the book is closed. Minor chipping is present at the head and tail of the cover. Overall, a solid copy in good condition, with only light cosmetic wear consistent with age and careful handling.
