Rusted pin

Thanks for reaching out to us. We may have a good match for this pin, but it's very difficult to narrow down the list of possibilities when the original is in this condition. Too many important details are worn away to get a good idea of how it was designed.

Before we go any further, would it be possible to see a photo of the pivot shoe that this bar interacted with? That may give us a better idea of what shape is needed.
