Links are molded in dark brownish plastic to represent the classic “track color” as seen in some paint ranges with each link made up of the track link and separate ‘plug’ with part of the inner link surface and the two guide horns with open holes that fit together as you assemble the links with each insert having track pins one on side and pin securing tabs on the other. There are enough links and horn plugs to make the 95 links per side with some spares.
