This pocket size slide rule is pretty rare because it is made of 4 pieces of thick glass. The brand is ALKU patented by ING (engineer) Kuhmann from Germany in 1946. It has the ABCD-scales and also an R-scale! The rule is in pretty good condition considering there is no case, and the plastic thin slider is also complete and without problems. The rule measures ca 18,5 cm or 7 1/2 inches in length. Check the video on how to work your vintage man tool : slide rule operation instructions!
