Paul,  Your memory is close; the upright player in the bowling alley
in the basement of the Biltmore Estate is a Cable-Nelson Dulcitone.
I didn't ask the docent if it still functioned but I did point out
that the slant-top player bench was backward and he turned it around.

The next day I was antiquing and ran into another, very tired,
Dulcitone in an antique mall.  Having not seen one before, two in two
days I thought odd.
