Vintage hand powered tool. The round part rotates and 2 holders above the disc oscillate. Looks like it could hold a part and polish it?
The round plate is cast with a smooth machined top and edge. It has concentric lines machined into the top surface. It is a type of cast iron. In the photo you can see the magnet i have hanging from it.
The shop i bought it from didn't really know what it did but said they thought it was for polishing glass.
