A few points on recognition manuals, and what is historical for them.
1. The multi angle images of ship models is indeed historical for ONI manual—for warships. It wasn't done for merchants since there were not enough of a type to justify it. Course it's much easier to take shots of the ship model for what we have vs doing line art. Minor nit.
2. All merchant ships In the ONI 208-J bppks are facing LEFT. This is not arbitrary. the convention to sort ships had to do with: their engine (stack) position (mid or aft); superstructure layout (passenger, composite, split); bow and stern shaps and general conformation; finally, they coded the masts, kingposts, and funnels (M, K, F). This was deon from front to back, and for eas of use they put the bows left. The book was then sorted using those forulas as primary headers.
So if a skipper observed a raised foc'sle cmposite superstructure ship with a cruiser stern would be coded 15 from the book, then if the pattern of observed masts, kingposts and funnels was MKFKM, he'd find this in the book:

The numbers on the side view are heights of the crosstrees, etc they are next to.
