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!"
