Looking for info on a plow

My dad bought this plow about 35 years ago with no point on it. We have slowly started pulling all our old plows out and redoing them to make them useful (50+ walk behinds) and this is the only one that we aren’t 100% sure on manufacture or even what its for exactly. We are 99% sure its for either digging potatos or hilling them up. But we need to know what kinda point went on it, it currently has a mount jerry rigged on for a bulltongue, but we would love to have a picture of an original one, so we know what point to forge out and mount. Heres some pics, any info is appreciated.
