Dealing with the Production and Servicing of Aeroplanes, this publication was originally intended to be produced in 32 weekly parts during the 1930s but it became a period of such unusually boundless activity in aeroplane development, that this First Edition was subsequently extended to 39 weekly parts, all of which are present here, together with 39 accompanying data sheets which focus on a specific aircraft each week and were loosely inserted. This is a superb collection with a wealth of narrative information, photographs, illustrations and charts on pre-World War II aircraft during a monumental decade of aviation development.
