This is the only IDing feature on the plow at all. Other than the CASE stamped on the frame.

Any help or advice or pointers would help.
Thanks in advance!!!

That's a Allis Chalmers plow.

Sorry, not an allis. I didn't read all the captions. weren't the case plows called a Centennial Plow?

There are also super chief as far as I know

I am associate of Crescent Forge here in Illinois They are the last to make shares for these old plows .Did you take this share off this plow? Are you looking for new ones? There should be a number on the back of the old share. Earl

Appears to be a Case "Centenial" plow. Grand Detour was a part of Case for many years and Case maintained the name on their tillage line as Massey Harris owned the Case Plow Company.Kind of confuaing . but that is the history.

Earl-Il is your best bet

Yes, I took this one off. No, I have another one already. but i cannot figure out how it is supposed to attach to the frog
