This medallion is about 7/8" wide and has the appropriate matching nut with it. It's in good shape with lots of patina. On its face, it has the words Disston and Philadelphia. It appears to be made of copper rather than brass so I believe it quite old; perhaps from the 1800s. Included in this sale is a wood handle for a vintage Disston saw and some miscellaneous brass screws for use with handles and medallions. See the pic for more info.
