I think this may have come form a C, but not sure. I was thinking part of a planter drive or lift. no numbers, and by the looks of the back it may even be broken.
Thanks

Looks kinda like a trip lever on a baler to me. I replaced one about a hundred years ago so memory may be misleading.

Looks to me like the sprocket that goes on the C brake shaft to drive fertilizer attachments and some planters. The peculiar shapes on the back side are part of the engagement mechanism that was controlled by a rod from the Touch-Control arm.
