What does not fit is Antoines reply concerning the hardness...if it is a CF it would be very hard and not easy to lap....

I have had 4 Charnley stones, and I've been following the UK bay for stones and images for years now. For my stones, they weren't too hard. Maybe like a Belgian blue, but far softer than translucent Arkies.
All of them were 9"-23 cm long or longer, and always 1 3/4 ~4cm long. You have to try really hard to find a Charnley that's less than 8"-20cm. Unless the owner cuts it himself.
The sides and back side is always crude cut. No straight lines, and, it's a fact that it's extremely hard to cut a piece of novaculite.
Always soaked in oil, they smelled like old oil and couldn't keep water on their surface, even after a lot of lapping. This one looks somewhat porous-er than a charnley, and does not appear to have been used with oil at all. The color is much lighter, and that doesn't mean something, but the red line or spots are a somewhat common characteristic that does not appear here. You can also see in some of the Charnley stones flaking (a common thing for novaculite stones, especially Llyn Idwal and Turkish oilstones). The non toxic dots- pores in Charnley stones are almost always filled with a very fine red powder, Iron oxide, where, in this case, they look different.
And the overall image, the stone looks slate-y, nothing like a novaculite stone.
And, I wouldn't be surprised at all if the stone is a finisher.
