Ok the last chapter:
Here is the hone, dry, wet, with slurry. I lapped this hone and looked around for a razor to run on it...I really wanted to see what the hone felt like. I picked a blade that I do not tape for maximum feel of steel and hone.
The blade I chose was a blade that I would have probably touched up on a SG 20K before stropping. So it was close to being shave ready and in fact might have been with some stropping. I don't think this is the protocol for estimating a grit size but this is what I did. So the hone felt very close to a barber hone in feedback. In other words, practically none.
The razor after 40 trips on this hone with water, was stropped and put to work. The shave: fine. Would I do that again? Possibly, just to keep up the inquiry.
Anyway, here are the pics.

The last pic is of the chipping which I hope might lead to and identification of this hone.
