I see those on E-Bay and CL all the time.  Actually using those old lollipop sign bases for a carousel horse is a good application.  It would not be very likely to tip over with all that weight.
I have seen them on small tables as well.  I guess I would rather see them survive than end up in the scrap yard!  I just wish people would not try to pass them off as some "rare" Coke authorized item.
