Questions for moldboard plow experts

Bought a box of NOS IH plow parts at auction yesterday, box contains some 132001C1 shins marked IH Earth Metal--OK I know what those are, also some NOS shins marked IH 660020M1 I tried to cross the number to newer number and it shows up 179318A1 diamond finish shin price-- over $50 what are these things

Without dragging a stack of books out, I think that the 132001C1 shin will work with most common Super Chief bottoms. IIRC, they used clipped head bolts.

660020M1 is a Massey part number. I don't think that 660020-anything would be an IH moldboard plow part number. I've seen aftermarketers' lists that showed that some 3-bolt MF and 3-bolt IH Super Chief shares will interchange, but I don't recall seeing a reference for the shins interchanging.

CIH's Diamond-Finish wear parts are/were supposed to be harder, more break-resistent, and retain a smoother surface than their earlier parts, or parts from aftermarketers. The shins and molds used a mounting bolt that had an oval under the head. I think the Diamond-Finish molds and shins can be used to replace earlier high-speed Super Chief wear parts.
