This appears to be a reproduction of the Picket 120 plastic trainer slide rule, which was a very usable and accurate instrument. I still have mine, although I seldom use it since the advent of electronic calculators. The scales on this are A, B (squares and square roots), C, D (basic multiplying and dividing), C1 (C scale in reverse, allows division without reversing the movements used for multiplication and allows finding the reciprocal [1/x] of any number from the C scale by reading directly on the C1 scale), K (cubes and cube roots), L (logarithms of numbers), S, T (sine and tangent values for solving triangles directly). These are the basic scales and with them you could do the engineering calculations for many, many things. They are the scales found on a vintage Nestler Model 23 slide rule. The Nestler 23 was the slide rule used by Albert Einstein, Werner von Braun (designer of the Saturn V rocket), and Sergei Korolev (head of the Soviet space program). More expensive slide rules add LL (log log) scales. The markings on the Pickett 120 rule were crisp and clean, although the hairline slider left something to be desired. The markings on this slide rule appear to be almost as crisp as the Pickett 120, but maybe not quite as crisp. Like the Pickett 120 Trainer, this one is plastic and cannot be adjusted for the desired amount of drag or smoothness on the slider. Some said they had to clean a coating from the main parts of the rule in order for them to move smoothly. No manual comes with this, but it is offered by ThinkGeek and their web site has a basic manual from Pickett available for downloading and saving as a PDF. Numerous other manuals are also available free elsewhere on-line.Read more ›
