Glen wanted to know about the Simplex Piano Player.  I have one in my
collection.  It is a little unusual compared to the other push-up piano
players: it is equipped with a spring-wound motor to operate the music
roll, with governor weights to regulate the speed.  It plays Simplex
65-note music rolls.  It will play other 65-note music rolls with an
adjustment on the right hand side of the spool box.
