some sort of rollers??

Probably not really a tool, but I thought I would ask around. I got this in a bucket of rusted tools. Was really rusted together, so I soaked it for several weeks in molasses bath, with a few light wire brush scrubs in between. Finally it came apart and I could better brush off the rollers. I did it just out of curiosity.

Can anyone identify purpose? Does anyone want it?

Those I think came from sliding doors in Victorian houses. Pocket door are what we call them now but now the hardware is not nearly as well made. Those fit in mortise in the bottom of the door.

With the cover over the rollers I don't see how a door could roll on them. My bet is that the shaft to a foot powered grindstone rested on the wheels with the shaft coming thru the openings on each side.
