In response to John Tuttle's question  about serial numbers of
Universal Player pianos, I think they were made, for the most part,
by Kohler and Campbell.  On the hammer return rail there is a date
stamped as to when the piano left the factory.  The roll drive motor
also has a date stamped on it.

I started to track all of the players that I worked on starting about
25 years ago.  Here are a few of the serial numbers.  I wish I would
have started tracking them earlier and included the piano serial number
with the player, but at least I have some info on them.
