Who made this table? cant find anything like it to compare.

Stacked leaf sliding table of unknown origin.  31 H, 38 D and 53 inches wide at shortest.  With two leafs out on each side its 102 inches, and with all leaves out and smaller legs down its 150 inches long.  Appears to be mass produced but with no manufacturer mark that I can find.  Solid wood with veneer tops.  I would guess mohogany because of the color.    Bottom has large 2 "numerals 133454 stamped in the wood with an antique font.  Some of the separate hardware that appears hand forged have single numerals probably to help assembling the table.   To extend the leaves you lift a small lever that raises the main table top an inch via a small wheel so you can pull the two leaves out.  Once the two leafs stop you lower the lever and the table drops nicely level with the main.  To extend the last leaf you lift the same lever up raising the first leaf 1 inch and allowing the last leaf to slide under.  While extending the extra legs automatically drop down and lock to support the last leaf of the table.  Hard to describe the action.   I would guess its called a drawer pull or draw leaf table?, Dutch pull?  maybe mission style?  Cant find anyone else that has one to compare.
