I'm looking for the name of this piano roll of which a segment
appears in this Duo-Art Bulletin roll [of July, 1929]:

Steinway Duo-Art Player Piano, unusual

If possible I am also wondering if anyone happens to have a MIDI
emulation scan of the roll.

The video portrays one of the craziest reproducing pianos: a dual
player system that can play both Duo-Art and Welte Licensee rolls.

I have been wondering for a while what happened to this piano after
the video was made, if there are any more pianos like it, and who
owned it or owns it now. Does anybody know? Does this piano even
exist anymore?
