Very helpfull,Thx Jim,looked Blaireau up,he posted the stone,The demensions of mine are the exact same,may not mean anything tho,did not get this stone from him but from another well respected...

If you look closely at the label,to me it looks like a modern,purposley aged repro,just sayin.

No Sig on the label,no label on the stone,just one fantastic finisher:)
