I really like the U.S. Army intelligence report diagrams of the German panzers that were captured during WW2.  They have a cartoonish quality about them, but they are still very accurate.  They remind me of the instructions of the plastic scale tank models that I used to build as a kid.  Of course I still build model (dioramas) now as an adult.  Some of the model kits that I built as a kid were some of the cheapest and worst detailed kits, but as a kid I loved them and built them as quick as possible.  I have an old Aurora Panther tank in 1/48 scale that I think I will "speed build" the next time I sit down at my table...here's a pic:
