sea venom panel question

The panel is a Sea venom FAW Mk.20
I have two questions the pilots note`s state that the bottom right instrument is an oil temperature gauge the one by the panel is the one fitted in latter marks but while the hole fits the fixings are at the wrong centers so I assume there is a different instrument to fit, dose anybody know what it looks like ?
The pilots note`s do not say what the left hand instrument is and the hole is not repeated on latter marks of panel any suggestions?
If you see any other errors please feel free to say.
