868 Reitz-Expanded 10" Rule ![]() CLICK for BIGGER PIC ![]() CLICK for BIGGER PIC CLICK for BIGGER PIC |
13" / 10" plastic body Slide Rule VERY LATE MODEL, MINT CONDITION. NEW, mint condition FEDRA 868 sets with 2 part clear plastic case and manual (plus multilingual care strip), still sealed in the original factory plastic bag. Basic Rietz format rule with added features, has a black self-documenting scale arrangement and pale green slide. The slide reverse has Greek symbols, an odd bonus, and the instructions are well illustrated and very complete. It has a very unusual duplex multi-line cursor design that reads the rear scales without turning the slide, plus it has 3 log-log scales AND inch/cm rulers laid out to permit both physical measuring and unit conversion. The multi-line cursor does area of a circle, plus some other interesting stuff like horsepower conversion and iron bar weight. I confess I had never heard of this brand or physical design before we got these, but I am amazed at how nice a rule it really is. I believe it is a local house brand name for the Australian market, made by VEB Mantissa or a similar German maker. A very attractive rule, made in Germany. Great starter rule for older kids!
