Help me ID tank manufacturer, please

I am looking at buying this tank but trying to figure out whether I can drill it but the guy doesn't remember who makes the tank. And I don't want to drive up to test to see if its tempered before buying it (3 hours)

Is it not drilled already? Looks like there is an overflow in the corner.
