The slide rule came in a BLUE HARD PLASTIC BOX. On the back side
of the slide rule is a table with physical constants.

There is a Newer (1968)  VERSION (C)  in the Collection:

This slide rule came in a BROWN LEATHER CASE.  The scales are
the same, but the name »NESTLER« and the ID is printed on the
upper-right CORNER.  The scales are named  L,K,A/B,CI,C/D,P,S,T
and the SLIDER is colored GREEN.

   

There is an Older (1960)  VERSION (A)  in the Collection:
---------------------------------------------------------
This slide rule came in a  BLUE CARDBOARD case.  The scales are
the same, but the name »NESTLER« is printed on the upper-right
CORNER and its ID ( » Nr.0218-Darmstadt « ) is HIDDEN in the
BODY under the slider. It came with a  METAL-FRAMED CURSOR ... 

   

... The CURSOR GLASS was broken and is now replaced by PVC from
a CD-Case.  The 3 HAIRLINES are made  (precise!)  with a sharp
» X-ACTO «  and colored with a permanent marker.
