Hello Dale, I have been around a long time in this business. Over the years I wrote down most of this that you read. I have several hundred names of pianos with this type of information that I have been trying to get into a book. Being on the PTG Board has slowed that effort down. I am now working with the Foundation on the History of the Piano. We will see how that goes. I have built several very old action models that I display and give classes on at some of the Regional and National Seminars. I will be at the " P.A. State Seminar " this month Thanks, for your interest. Jack Wyatt
