Guys,
What with Peter's current search for a seat pan, and with time provided by staying home, I went back and read/re-read all the posts in this topic I started. It occured to me that, at the time, I was completely buried at work and did not give full due appreication for all your interesting posts. So, a year-and-a-half late, thanks for all your ideas, stories and recognition of my project.
Richard L.
