Logomat 2001 Pfiffikus circular slide rule Paragon 1960 Germany

This very small circular slide is called the PfiffiKUS 2001 and is made by Logomat from Germany, which was sold as a promotional gadget. This one is printed for a Dutch printing company called “paragon”.  The PffiffKUS als had a practical use since it was still able to perform many easier calculations and was marketed as a “calculator marvel” in German “Rechenwunder”. It comes on the original black book like case and has the original manual (in German) as well, so full set. The slide rule is hardly used and working perfectly. The slide rule measures only 5 cm or 2 inches in diameter (plastic cursor comes outside this diameter).
