<html> David, I have a chart posted on Kawai's web site regarding Kawai grand models over the years.  It doesn't have the years of production, but it shows what the sizes are and their relationship to other models by scale.  <a href="http://www.kawaius.com/" eudora="autourl">www.kawaius.</a><a href="http://www.kawaius.com/" eudora="autourl">com</a> click on Tech Talk. Kawai's upright models are beyond my understanding, except those sold since 1995 when I started working there.
