The December 2001 issue of Fast Company magazine has an article about a
very expensive wall hanging organizer called the Uten.Silo. (Page 42)

In the photo the various compartments are filled with quite an
assortment of items including a plastic pocket slide rule.

I can't tell what brand it is, but the scales are: A / B CI C / D K.

The photo can be seen at

but it is too small to see even see the slide rule (it's the white blob
just over half way up the left side).
