Thanks as always for the replies.

Will, it's odd that you mention that because the ribbed bar is smooth and round near the 'eye' where the link is. About halfway down the bar is where it is more squarish, has the ribbing and has two seams on either side. I'm guessing that it was once ribbed all the way to the eyelet, but was hammered out to be more rounded. Note the odd thickened end piece where the spikes spread out. This doesn't appear to be brazed or welded on. It was part of the whole bar! The whole construction is fascinating and confusing at the same time. This piece is solid and not flexible at all like modern rebar.

Rick, your point is well founded. Of course something this thick undoubtedly wasn't made by twisting. I guess I was just thinking aloud. I had proposed cast, but hadn't thought about stamped iron. Still, considering its age, I'd assume cast more likely. The earliest stamping where from trip hammers used in the 1830's, I'm told It was the start of the Industrial Revolution.
