One Piece Ivory

[Roger Jolly]

Hi John,
            One piece ivory was used by both Yamaha and Bossy, but I've
only seen this on post war production. I would be sceptical with regards to
Sherlock Manning.
A little spot of acetone on a cloth and dab it on the tail of the key top,
under the fall board felt area will proove it for sure.
Regards Roger

this crack to distinguish between ivory and plastic.

Manning are ivory! I say they are plastic because there's no separation
between head and tail. She says her parents bought the piano when she was
nine and, except for a time when she ran away from home at 19 to get
married, says that the keys have NEVER been recovered in plastic.

are they?
