Comments:

Obtained from a friend who inherited it from his uncle who was a lapidary worker in Mississippi. Both the wheels were worn to hollows when the machine was first obtained. After plugging it in to get it running the first thing I did was dress the wheels to flat surfaces. The left (medium grit) wheel is dressed-down to 7¼" in photos, the right (fine grit) wheel is dressed to 7½" in photos. The motor is a Westinghouse 1/2HP 1725rpm, 110V.
