I haven't seen it in years, but there is (or at least there was)
a roll operated Welte Philharmonic organ with playable console and
separate roll player cabinet at Scotty's Castle in Death Valley
National Park, California.  The place is preserved and open to the
public so I'd think it was still there.  The first time I saw it,
it was operated by paper rolls.  The next time I saw it, it was
operated by computer to preserve the rolls.
