A Rotating Table

This table from a recent auction seems ordinary enough.........

But it has a unique feature...............

It rotates! It will turn all the way around.

Not sure why though. Our guess is for playing cards or some other game. But that may not be right because it's more end table size than card table size.

The legs were pretty distressed looking, but I liked that. I just cleaned them and put a wax sealer over the old varnish. The top was more scratched up than distressed, which made it rather ugly. A coat of black paint, some sandpaper and more wax solved that problem.

What do you think it was used for originally? Why the rotating top?
