I received this stone from my Grandfather, on the back it reads:
Lavoy
T. Noonan & Co

First pic is the back, second close up of engraved label, and last is the top.
This stone is very fine but I haven't really put it through the paces as I wanted to determine what it is before putting oil or water on it.
According to what I could find T. Noonan was a barber in Boston during the last quarter of the nineteenth century. My gut and all logic says the stone is a finisher for straight razors.
Admittedly I have little experience with stones other than very course cheap ones and the cheap DMT diamond plates. I've been using granite and abrasive film so I can't compare this stone to anything.
David Weaver, I'm hoping you can help me!
