I have a 1912 Henry F. Miller with the uncommon Miller player
action that has been repaired as needed but never rebuilt or restored.
It still has the original pumps, valves, 82 of the original note
pneumatics, the original strings and tuning pins.  New hammers and
dampers were installed in 1999.

There are many great restorers that visit this site and I would like
some opinions on what you think of a player that still has so much
original material in it.  If I pump with no roll, all 88 notes play
at once.  I think the material used in this piano must have been of
very high quality to have lasted so long.  Some sights and sounds here:
