Of the two horns of the C, one hangs onto the towing U bolt, and the other horn holds the towing cable loop. The rectangular devise between the two horns is moveable and raises to lock the clevis to the U bolt and the towing cable so neither end will fly off. The clevis is made of cast steel and is presumably factory painted in the current base color. With use they will have a lot of chipping, rust, and worn bare metal spots.
