All, There were several pianos that had one piece Ivory. Yamaha was one. Several years ago, I had to replace a whole bunch of them on a vandalized 7' Yamama. I obtained the replacements from Yamama. (I don't think they have any available now.) As I purchased a whole set, I still have a bunch in the key locker, if you need some. As an aside, I believe Rick Wheeler of Roseland Pianos, is installing one piece Ivory, on request. (Yes, it is still available, but it's very spendy!) Regards, Joe Garrett, RPT, (Oregon)
