Rare antique sharpening stone in original embossed painted cast iron case. Embossing reads "India oil stone manufactured by Norton Company sole agents Pike Manufacturing Co Pike NH U.S.A." This is a natural stone and the "manufacturing" is just in the cutting. Stone is a light brown color and marked on end "medium India" Stone measures 6" x 1 11/16" x 3/4". a few small edge chips. Seems a cast iron case would yield more chips than a wood case. It is a very well made and expensive case that once had 4 round cork wafers at each corner. Original black paint has rusted through on top. . Buyer pays $12.00 mail.
