Thread: Evatt Cast Steel 1700s?

Bought this today. This is the current state after a few hours of work. You don't want to know what this thing looked like when I got my hands on it. In a cocoon of corrosion. Astonishingly, despite being pockmarked, it has a fairly clean zone at the edge where I think it is quite viable! Idea of age? How far do you guys think I should go on the restoration front?
