Replace all the key frame felts, including cardboard punchings. I don't like to deal with dry-rotted punchings down the line. Might as well replace the letoff buttons as well. For the hammer rail, get a roll of fine emery cloth from Klingspor and adhere a strip onto the rail with double-sided tape (a hardware store will have 1/2" tape for plastic window sheets by 3M). -- Regards, Jon Page
