Thanks for the reply about sales of single discs. I think that more would be
sold, but ....

We have sold to other high schools in Colorado,
Cherry Creek School and Windsor High School, for example. Perhaps it might
be helpful for you to contact their physics departments.
I know the man in Windsor, he would help but he is too far away. I work in
the Cherry Creek schools. Can you tell who was the actual buyer/ orderer.
Where was it shipped? There are several schools. If it is easy for you, it
will save me some effort and time.
