Hi Jerry, Player keyslips are in two pieces as you described. The front slip is usually hinged with SOSS hinges (invisible). When idle for a long time they tend to freeze in position. For re-blackening sharps I steel wool them to remove dirt and grease, dye them with _black_ leather dye. When they have dried I spray a couple coats of Deft Clear Satin. Debbie Legg
