I bought this stone and the guy had said it came from an estate sale. It was in a sale with a lot of stuff from what appeared to be a forge (anvil and misc. tools). The first picture is out of the wooden holder so you can see it how I received it. Dirty. The next picture is after lapping it and removing the dirt on the good side. The next is a little of the slurry. It is 2 inches wide and one inch thick, 8 inches overall length.
