I'm afraid I can't tell what you have based on these images. I cannot see the shape of the glazing. I have a few ideas what you may have, though, and I've related a few parts to this discussion that I think you should consider. You can see them on the right side of this page.

If none of these are a match, I will need you to remove a small, undamaged sample and take a few pictures of its profile so that we can see its shape. See the video below for more information on exactly what kind of shot we need.
