Marx and MPC both used 2-piece molds for Stegosaurus. The MPC figure is substantially smaller and much thinner than the Marx original. I know of two different molds for the MPC Stegosaurus. The figures from the two molds are identical except for very tiny difference in the positioning of the markings. Also, one is marked 18 on the outside of the left foreleg, the other is marked 8. Markings - 20 LONG (left side of tail), STEGOSAURUS (right side of tail), 18 or 8 (outside of left foreleg) |
