REMARKS:
==============================================================
This model is made of aluminum. It came in a box with manual,
and a leather case, which can be clipped on the user's belt -
typical for the USA: As seen in the "Western Movies" ready for
a "quick draw".

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

The label on the box says: "3 moon flights; Pickett rules have
been aboard 3 Apollo missions; Proof of Pickett precision!"

Historical Remarks ...
