Well, the picture is up.

Any opinions as to whether this bore has been relined?

I notice that when you look closely, you can see small straight lines radiating outward from the bore, like little spokes in a wheel. These seem to line up with the edges of the lands that are inside of the bore.

I have never seen any markings like this before, and that is why I started wondering about a reline.

Thanks for any opinions. (Won't hold you to em.)
