Recently received this “pair” of water hones from a Canadian auction site. E. Co. Cup or chalice label suggests an early Escher & Co. hone. The single Red cardboard box with “stapled” corners seems to fit perfectly for the stone. Both stones measure 5” x 2” x .4”. As found photos. Appreciate comments and discussion from those familiar with old Escher stones. Thanks, Austin Attachment 344606Attachment 344607Attachment 344608Attachment 344609
