==========================================================
The slide rule came in a blue plastic case with a booklet.

Observe the » MEISSNER « in the headline of the booklet:
The same model was previously under the logo  » MEISSNER «
on the market ...

Historical Remarks ...

Unfortunately this slide rule was found in a flea-market
with broken cursor windows.  Replacements were made of PVC
from CD cases:  The hairlines are made (precise!) with a
sharp  » X-ACTO «  and colored with permanent markers.
"MouseOver" the cursor in the picture above to get a
DETAILED VIEW of it ...
