I removed this plate from one of the pieces of equipment located in one of the engine rooms. I discovered that various crewman had at various times removed this plate to make their mark so to speak. I have cleaned a small part of the front of the plate as it was covered with encapsulate during the scrapping of the ship. The white specks can be removed with goof off and the metal polished. This is a nice historical piece from the ship. A most interesting historical piece.
