I'm not sure if this is a really old Incra or some China-made table and fence system.
Looks like to me the fine adjustment is by a screw and crank at the front of the table, notice the rod running under the table at the round hole that looks like where a router would mount, but I'm also not sure what that is that looks like a router red bit behind the fence in the slot in the table. I also notice that the legs for the table are held together with cross dowels or barrel nuts, not common to USA made tools.
I'd really want to see this in person to see how everything operates.
Is it worth $100, I would say probably.
