Some would jump to the conclusion that this is a mounted surface plate, but almost everything is wrong for a mounted surface plate. The stone measures 36x24x4.5”. Table top height is about 42”. Total table weight is about 760 lbs. Stone’s original color is bone white. The stone’s mounting is very tight on four sides and on the outer 4” of bottom surface. The tight grip of the table on the stone is all wrong for a surface plate. So was this for some kind of hot work or what?
