A progressiv duplex sliderule from Aristo, in 3 different versions. The two newer ones have the most obvious enhancement together: the rubber feets, which enable a one-hand working. Furthermore are variants of scales remarkable. Apart from the second tangens-scale was the numbering changed.
The oldest cursor is partly metall, only the two newer models have a full plastic cursor.

To the sliderule belongs a ruler with centimeters and normnumbers (sorry, my dictionary provides no translation, so, if you know the correct term, please email me.) (e.g. Aristo Nr. 1367), and a table with conversions (e.g. Table A, here in an older and a newer version).
