The ad reads like these were once made by Porsche, right? I’ve never seen a Porsche stub like this. Looks aftermarket to me. Maybe I’m missing something since I’m not looking at the actual ebay description.

That’s because we are used to seeing them rust covered. Uhmm, I mean with patina. (IMG:style_emoticons/default/happy11.gif)

Like you, I’m a bit surprised to see the induction hardening and wondered about the part. I would have thought they would be oven treated which results in a black / blue oxidation over the entire part. But it is plausible that it was induction hardened, Germany used to be a manufacturing powerhouse. Or, could be a part produced later for service after induction hardening became more common place and better suited to small production runs vs oven heat treat.

It is interesting to see one untouched like this. (IMG:style_emoticons/default/beerchug.gif)
