It originally came from a dental laboratory and was used to touch up scalpels, it's quite small 4"x1" and the surface is extremely hard and glassy.

Tam o Shanter perhaps?
Looks a little like a HARD ARKANSAS stone
I've got a medium on my tri-hone that looks similar, that same marbled look.
I was thinking TOS myself, I haven't seen anything else that looks similar so far, the slurry is very pale milky white, I tried it out on a new scalpel blade, 50 odd laps on the flat of the blade and it does remove metal very, very slowly, I'll make a new coffin for it as the original leaves a bit to be desired.
thats not a ark i was thinking a tos but i could be wrong i havent been able to play with one yet

The above close-up is mine - of a white tam (half of it is wetted). There is a distinct difference in the grain pattern, to my eye.
I know that arks were provided by laboratory suppliers to hospitals, etc, for sharpening lancets and the like - hence 'surgical black arkansas' but these were, well, black!
I don't really rate tams as that slow either - some cut reasonably quickly.

It looks like an arkansas to me...
My first glance read it as an Arkansas, and the provenience would suggest that. Alx
