Jody,

For my 2 cents' worth, I will add that the contraband material [Ivory]
was not solely used in pianos and organs.  Several cylinder music box
manufacturers, particularly Mermod Freres and Conchon, used it for
decorative keyhole escutcheons, which I have had to replicate many,
many times in my workshop.  As it happens, I found that old piano
keytops work just perfectly as a source to cut these replacements from,
thus maintaining authenticity in both material and colour.

Respectfully,

 [ I'm not surprised that this material found its way into other
 [ items of "artwork".  I'm pleased to see that there are constructive
 [ ways to recycle Ivory from discarded pianos.    It seems a shame
 [ to let it go to waste.    -- Jody
