The bottom picture, (post 14) showing the hitch, indicates to me the definite possibility of the plow being a
J I Case. Case had the Eagle Hitch 3 point hitch, from'54 to early 60's. It was an early version of a quick hitch and was not capable of swinging. To cure that problem the lower 3 point hitch mounts on the implement had a center pivot to allow the implement to "wag" behind the tractor. There should be a pin hole to keep it from swing, for use with "normal" 3 point hitch tractors. I see the large nut in the center in this picture.
Also, the gauge wheel has a really long hub, (post 15) which Case also had. Case implements in mid 50's had green trim/wheels. And the other color is Orange, not Red. It shows in some of your photos.
I include these pictures of a Case with a disc plow. This disc plow is NOT like yours because this one is adjustable to maybe throw left or right without turning over. The tractor, Case 400, is equipped with Eagle Hitch.

I've tried that and got nothing. I've emailed a few people that deal I'm older plows but haven't heard back. I'm thinking I'll order an induction bolt heater to get one off and see if I can find a steel casting place that'll cast the parts for me. Then I'll just have to get someone to make one arm and find two scraper blades.
