N80 said:I saw this plow on oBoy:
It was reported to have come off of an IH 300 tractor. It has some type of otwo-point quick hitch deal. Its not the same as your plow but it does have a peculiar spring trip like yours. So maybe yours is an International of some sort. That seems the best guess any of us can offer.
Just taking a stab in the dark.
