This book is basically an English reprint of the Flugzeug Profile on the Ar 240. This book is useful if you are interested in the operational aircraft of this type or making the Revell model as it has some very nice photo's but unlike some of the others in this series it does not really cover the prototypes and developments to much. Profiles of the other versions such as the BMW 801 J powered prototype would have made this an excellent book. There is not too much around on this aircraft so for that reason I would recommend it.
