For sale is a vintage Lego Tyrannosaurus Rex figure, set number 6720, produced in 2001.  This set is nearly complete piece-wise but is missing the two dark gray slope pieces that go on its back as well as the tail sections needed for some of the alternate dinosaur builds.  Additionally the "tongue piece" has been swapped for one of a different color (it should be red) and one of the body quarter segments has been swapped with one from the mosasaurus set (it has a different pattern).
