Kevin is right, I've got my hands on a fair amount of some pretty unique iron here. We've had loads come into the shop over the years, but the working qualities of this stuff is worlds apart from other varieties of wrought I've dealt with. I do have other, coarser varieties available if there's interest but I wouldn't expect this particular material to be around forever.
If you're interested in this material, feel free to message me here on the boards or through my email address: email@example.com
I don't currently have any blanks on hand, but I am going to make some up soon in anticipation of demand. For future orders, please allow 2 weeks from the time of payment for delivery as I'll need to take some time to process the material into a suitable shape.
And speaking of a suitable shape, I believe the ones pictured in Kevin's post are approximately 170g and 3-4mm thick.

I recall there being a few I made that were more in the 5-6mm thick range and maybe 7-8cm across the face. Those sold for $110, and I think a good guideline for expectations if you're looking for a custom size (which I am more than happy to do
