Everything in this anime looks like Honda.

It is very clear that this OVA series was animation supervised/directed by Takeshi Honda. But since there are other animators in this one, he didn't animate everything by himself.

This makes me want to find vehicle manuals. Those manuals have detailed illustrations that disassemble vehicles by part. I had luck with finding manuals for disassembled firearms, but the vehicles ones are weirdly expensive in print and hard to find online.
