When I first subscribed to the list someone had posted a question - answer type discourse to this grey market piano problem. I tossed it out unfortunately, but I do remember it stating that grey market pianos had two plastic strips tacked to the left interior side of the piano just below the lid. Supposeibly in Japan they were to hold the documents that came with the piano. My two grey cents worth (those 1943 steel pennies). Doug Mahard
