Ivory keytop substitute

[Ted Simmons]

I tuned a Mason & Hamlin AA today that was in pretty good shape except that
the keytops were a mish-mash of ivory pieces, most of them were installed
without whitening underneath.  The keyboard looked horrible.  I tried to
talk the owner into getting new keytops but when I mentioned plastic he
cringed and refused to accept any material but ivory.  I haven't heard of
any ivory substitute lately.  The July 1995 PTJ mentioned using bone but the
price was pretty high.  I think if I could show him a sample of a non-ivory
keytop that looks and feels like ivory he would be happy with that.  Any
thoughts out there?
