The stock Datsun 1200 Rocker cover uses a push-and-twist oil cap. It is a classic all-chrome cap and seals with a simple round gasket. Some other Datsuns use a threaded cap that will not work in a 1200. By the way, this is where you add oil to the engine.

Datsun 1000
The earliest A-series engine, the B10 Datsun 1000 A10 engine, uses a vented oil cap, so it doesn't work with the 1200 (Datsun 1200 caps are sealed). Vented cap is also known as a "blowby cap" because fumes will come out of it -- visibly so when the engine is worn. 1200 uses a sealed cap for happy motoring.
USED BY * R16 engine (Datsun Roadster) * J13 engine (Bluebird 411, Datsun Trucks 521, 620) * H engine (Datsun Roadster?)
Datsun 1000 used one of three varieties of oil cap
* plain blue * plain blue with Nissan text overlay applied * Elephant cap
The regular 1000 oil cap is plain blue with a little arrow sticker.
Datsun B10 Elephant Cap was used in some markets. Apparently the elephant oil cap is a JDM OPTION cap

Subtle difference between original and repro caps. The cap on the right has no arrow:
The following is reportedly from 1000 coupe brochure, but looks very much like an A12. Did they make an updated A10, or is this a prototype Elephant Oil cap for an A12?
Nissan
Later Nissan replacement caps differ stylistically from the original but work on all 1200 engines.
B34
At some point during the B110 era they updated the cap by putting writing on it. Possibly 1973?

I bought a brand new oil cap last year from Nissan Parts Business (Japan) for about $15 USD. It was the gold finish kind. The original plain silver type has been replaced by the gold type.
