I got this hone at the last week (or should I say rock, as its a big lump)
Im guessing its a Charnley Forest I have looked at ALL the threads on the stones here and in the wiki alreadyAttachment 165831
It was an arse to lap (it was not dished much, but still needed lapping) I seem to have lost most of my weekend on it lol. Im hoping to get some razors onto it next weekAttachment 165832
Its a lovely looking stone and im happy to have it.
It did come in a wooden base, it was in poor condition but kept the stone safe for years so cant complain too much.
