Kagero’s Top Drawing books offer the modeler a good reference for rivet patterns for those so inclined. Also, they are great references for those trying to accurize a kit.
This book contains six view drawings, top and bottom plan views, left and right side profiles, and front and rear views of all four aircraft types, A-D versions in 1/72nd and 1/48th. The 1/32nd scale drawings are actually on a separate foldout and only include the B-1 and D models. There are also some detail drawings of internal items, such as seats and instrument panels included. Cross section drawings are provided for the scratchbuilder as well. There is also a small drawing that shows the external differences.
If it was just drawings and riveting diagrams, then it wouldn’t be from Kagero. Besides these, there are five color profiles of different models. They are first rate drawings.
