A compact, “5 inch”, Model N1006-T scientific slide rule manufactured by the Pickett & Eckel company in the mid-1960s. The slide rule differs from many other units not only in its compact size but also in the fact that the main body is made of aluminum. The slide rule incorporates 17 scales and came with a belt-mountable leather case. A leather tab at the back of the case assists with extraction of the slide rule from the case.
