Guys, I don't know anything about Charnley Forest stones,
but I remember reading a few threads in which I saw there
was much interest for this hone.

I was searching Ray Iles's site for woodworking tools and
in the sharpening stone link, I saw these hones listed in
three different sizes:

Charnley Forest oil stone 9" x 2" (boxed) £28.00
Charnley Forest oilstone 9" x 2" x 1" (half boxed, lid only) £25.00
Charnley Forest oilstone 8 1/2" x 2 3/8" (in tatty box) £25.00

You can call him at 01507 525697(UK)
He won't respond to emails I read somewhere. So if
you have interest in a CF, call him.
