Logomat mini 2000 circular slide rule 16 inserts full set 1960 Germany

This unique slide rule system was produced by Logomat from Germany. It uses separate small discs for separate specific calculations. This methode allows for a longer scale for every intended calculation. It has separate cursor and a magnifuier on top that also holds the small disc in place. This is the most elaborate model (16 discs). It is entirely constructed in plastic. Even though all small discs are in mint condition the back of the slide rule has the smallest crack (which does not affect use) and the hard acrylic cursor has some cracks as well (still performing it job correct). I tried to show this in the pictures but it is hard to see. The price is adjusted for this. It comes on the original book like case and has the original manual as well. A rare complete set. The slide rule measures ca 9 cm or 3 3/4 inches in diameter. Check the attached video on how to work your vintage man tool : slide rule operation instructions!
