Carborundum # 115, New To Me.

Hello,
I got this Carborundum # 115 this week. I like collecting the old Carborundum stones. I'm happy with this # 115 because it's the finest grit Carborundum that I have in an 8x2 inch. I want to put the grit at 1000, but cannot find proof of my guess. The old Carborundums are hard to find documentation on, at least for me they are. I will set my next bevel on this one, just to see how it compares to my Norton 1000.

Thank you for looking,

John
