Has anybody ever seen a Hupfeld Unioliszt player piano?
I cannot find this instrument in any catalogue or in the
literature.  Is there a description, a catalogue or an
article about this instrument?

Niels Berkers has found the Unioliszt in the Netherlands
and he tries to find more data.  Who can help?

Thanks in advance,
