I'm back on the list - my computer has been unwell and in traction.
Answering Daniel Wilson about my Duo-Art Pedal-Electric: no, it isn't a
"one-lung" model, but a full Duo-Art with expression for both theme and
accompaniment,motor-driven, plus provision to disconnect all
reproducing elements and play it as a foot-pumper.  It's called a Pedal
Electric Duo-Art -abbreviated to  PEDA.There weren't a lot of these
made - see "Restoring Pianolas" by Arthur Ord-Hume (pp. 64-65.) Arthur
refers to the existance of these "probably only in Grand format" but
this is an upright.  (Incidentally you'll see a credit to me in the
book, being thanked for allowing the author to visit my collection.
However to the best of my knowledge Arthur hasn't yet graced these
shores with a visit although there is a photograph of a barrel-piano
with a cracked soundboard that looks suspiciously like a picture I took
and sent to him for comment many years ago.)

To answer Daniel's other questionthe wording on the fallboard is just:
"Steck Pianola Duo-Art." The piano needs a full restoration which is on
the priority list but not at the top. Like many Kiwis I'm just
awakening from my winter hibernation, ready to enjoy the Southetn
summer.

Best wishes to all.
