Clawfoot Table with 2 leafs

 This table is very heavy and has clawfeet on wheels.  Underneath it has a very old looking hand  crank to extend the table so you can add the leafs.  I'm not sure if they chairs came with this table or not, but the backs of them have an acorn with leafs pattern.  They're very pretty.  Any help figuring out where this item is from and how much is worth would be very appreciated.  Thanks!
