REMARKS:
==================================================================
This pocket model is made of aluminum with a "Lifetime guarantee".
It came in a display box with leather case and a 96 pages manual.
With its 32 scales it belongs to the most »loaded« slide rules!

This slide rule has the typical "Pickett-Yellow" body: The "-ES"
in the model number means "Eye-Saver"; Models with the "-T"-Ext.
(for "Traditional") have a white body.

On the box the term "synchrolog" stands for the combined LogLog
scales: They are designed as a uniquely, split long scale, and,
because LL+/- are reciprocal, 2. & .5 (eg.) share the same tick.

                     Historical Remarks ...
