Hi, I bought these two piece which both belong to each other. The small one it has a hallmark of R&H .900 and on the larger one it has a mark of just .900. I need help identifying the piece. http://i54.tinypic.com/27zm35w.jpg http://i52.tinypic.com/5plamu.jpg http://i51.tinypic.com/k0g6jp.jpg ht...
