Here is a suggestion, but it will take a little work and research on your
part. The Patent Literature is full of designs for dozens and dozens of
viewers. You could go to IBM's Patent Server and search for them. The
Patent Front Page lists who holds the Patents and often an address. Also,
it will tell you who the Patent is assigned to.

That should give you some leads to follow.
