What is this circled in the photo, AC2W engine?
I've seen alternators wired to this, is it for an ammeter?

To me it looks like an oil pressure switch or engine temp sender

Not sure cobbadog, like I said I've seen alternators wired directly to this sensor which made me guess its for an ammeter but also tachometers (rev counters) are wired from the Alternator sometimes

???

I'll wager 20 Attaboy's it's oil pressure sensor or safety switch.

It is basically an oil operated switch. Your engine appears to be an AC2W marine engine. This switch was used to energise the charge alternator whenever the engine was started.
