Norton does make and have made quality hones for many years. I have my grandfathers Norton 'Queer Creek' hone he used to spit on when honing his razors. Not sure when it was made, maybe in the 1940's, because they changed the name from 'Queer Creek' to 'Clear Creek' around 1946 or 1947.

The hone is in very good condition, I keep it in a wooden box for protection. Have not honed a razor on it in years, not sure what grit it is but may give it another shot to see where it fits in the progression mainly to get an idea what grit it is.
