Further comments This slide rule produced for the German army under a code name: "cme".  CME is the code for Wichmann. I strongly believe the slide rule is manufactured by Faber-Castell: it looks and feels like a FC, but also Faber-Castell produced a lot of types of slide rules for Wichmann.

Besides the fact that the slide rule is bigger than normal, it has a very sturdy design:

The slider has small indents on the left and rigth (as can be seen on the photograph). In the top and bottom walls of the well are 4 small metal spheres. The indents lock on the spheres, sothat the slider cannot accidentally drop from the slude rule.

The cursor cannot easily be removed from the stator, due to the mechanism show on the detail photograph.
