REMARKS:
===========================================================
This historic wooden model is the follower of Model »No.21«
On its back side are conversion tables in French.  The
slide rule came in a black cardboard case.

Historical Remarks ...

Both Cursor glasses were broken und replaced by PVC - The
hairlines are made (precise!) with a sharp » X-ACTO « and
colored with permanent markers.  Notice the non-symmetry: 
Following the build-in mark on top of the cursor ( refer to
the lgX ), the cursor marks had to be made out of center!
"MouseOver" the cursor in the picture above to get a
DETAILED VIEW of it ...
