This table looks to be either a completely hand-carved piece of amazing work, or more likely a hand-carved piece of amazing work for the table top, and an older, mass-produced base. I am not entirely sure.
What I do know is that there is no metal used in this table. It is all wood fitted together. It expands to twice its size using a wood system.
I've included some pics. You must take the table and chairs, but you can do what you like with the chairs as they are reupholstered mass produced chairs in average condition.
