Now that I have moved and semi-settled in...

I busted out my Rolls and looked at the stone. It appears dark grey-ish/brown-ish when dry and looks a very dark brown when wet.

It has MADE IN ENGLAND stamped/inked on the back.

It seems to be VERY coarse for a finisher, but I haven't lapped it since it's so damn thin. As I get more time I will mess with it a bit more and report back.

I still may lap it, since some of the corners appear very smooth in finish. I dunno, I still don't want to have it break and never be able to use it.
