Further comments This is the first forefather of the succesful line of business slide rules of Faber-Castell. It only has 7 scales, but already the characteristic that the upper scales are centered around 1. The translation tables for English currency are printed on the back: in later types they are changed into special scales.

This slide rule has an inch-scale on the bottom and a centimeter scale on the top.

This particular specimen looks like it is nearly brand new.
