Query: Weak on Substance, pretty pictures

The book is apparently aimed at model builders as it has many full color pictures, but little hard data (for example, how long was this beast? Don't look for it here. What little information is provided is hidden among the text. At the very least a book like this should have several tables of characteristics for each major model. I will not be purchasing anymore of this Osprey series.
