eems weird to put that label on it that talks about making sure you have oil. "NOT INSTALLED ANY OIL ON THIS ONE!"

Like someone bought a valve cover from the local Nissan dealer 35 years ago with the intent of making it a show piece or collectors item?

I think.. someone bought a new engine (with the message: no oil in this one) and installed the cover of the replaced engine and now the new engine's cover was obsolete.. and has that sticker still on.

Aitoku is a firm that deals in engines probably?

btw. my 1979 280zx has also a yellow flaky valvecover, it's still original.. nothing done to it yet..  (if you ask me these were coated with some blank paint)

I wonder if from factory they used a clear chromate conversion coating like clear alodine to give a small level of protection. 

The early 240s valve covers I've cleaned (usually with lacquer thinner) had no coating. I believe that's true of the later ones too.
