Langworthy owned the HHR mold. Wico began their own molds, a plain rim with or without printed inserts. The inserts were rectangles similar to Bud Jones or "jagged crowns." They also made split inserts like Bud Jones. After a couple years, WICO was bought out by RT Plastics, who kept the same designs as Wico. A few more years and Langworthy bought out RT Plastics. Are you thoroughly confused, yet? That is why all of these molds are sometimes called Langworthy.
