$60 · vintage grinding wheel

Early 20th century, circa 1912. This grinding wheel was made by the consolidated optical company. I believe they were out of business by 1915. This thing is solid and heavy, cast iron base. The wheel is extra fine, maybe Arkansas stone? ( Note that the 1949 on the plaque is a model no. Not a date ) My plan was to mount it to a treadle sewing machine base and use it to hone my chisels. Another project I won't get to. Call,text, or email 250-208-2412
