For Sale By Owner

The Sama & Etani Circular Slide Rule and Concise Chemical Tables was manufactured in 1969 in the US and was considered revoluntionary due to the small size (7.5 cm wide, 11 cm high) and thinness (2mm thick) that allowed it to fit into your shirt pocket. The nomenclature is engraved, not printed so it will last forever. Printing on the back and an additional slide in card summarizes: periodic table of elements, mathematical formulas, alegebra, trigonometry, geometry, analytical geometry, chemical and physical data, gas constant values, greek alphabet.
Still have the original owners manual that tells you how to use the rule and also the protective slip on vinyl case are included.
Except for some markings on the vinyl cover, it is in perfect condition.
