This is a vintage Norton Abrasives HB13 Hard Arkansas Oilstone in unused / new in box condition. (light handling on the outer box only) This is a non-Randall issue stone that is very similar to the much more expensive late 60's / early 70's SP-13's -- a great replacement stone at a fraction of the cost.

3 photos for preview -- the purchase price includes shipping to delivery addresses in the USA only. I have six available -- thanks and good luck.
