 Subject: FS: Steinway Duoart

FS: 1923 Steinway grand w/Duo-Art reproducing mechanism.  Hand painted
art case.  Choice original condition.  Player mechanism is tight and
plays.  Piano action is that of an unrestored 1923 piano.  Comes with 60
old Duo-art rolls.  Restore this treasure and you will have a $50K
instrument.

If you are seriously interested, I will send you an Email attachment
JPEG format picture and would like to communicate with you via an old
fashioned method called the telephone.

Thank you.
