Not absolutely original, but if you don't like the look of rust most of the vendors and
many FLAPS carry Dupli-Color DE1651 Cast Coat Iron paint that looks pretty natural on
the running gear. There are a few pictures at the top of this page of an SM420 ready to
install that was painted with the DE1651:
