6"/5"Pocket Slide Rule
MINT, Factory Boxed Bamboo, Log Log Duplex rule, metal framed glass cursor. This is Hemmi's original pocket duplex rule that was later released with a different scale organization as the POST 1461 Versalog. This has blue and red scale markings, with adjustable metal end braces and cursor. Note that this rule has BOTH A+B scales, missing on the original Versalog.
This is a wonderful lightweight rule, complete with box, factory manual, and brown leather case. Pics are the ACTUAL SETS offered (except for the reference pics above).
Everything is in excellent condition, the rules are still in sealed factory bags, the tiny bit of green verdigris on the brass screw heads buffs off easily with a soft cloth and a bit of Windex (we will open the bag and clean it for you, on request). We see these sets every so often, but MINT sets like this are very rare. (RH)

Walt's personal pick as the best designed, most readable high end pocket rule!
5" Pocket Multimath Duplex Slide Rule
Nestler's most complex pocket rule, BRAND NEW late production rules, with companion data ruler, and leather case. Has 8 Log Log scales, P (Pythagorean scale) and double length R1/R2 scales for roots/squares, with a 6 line cursor. Also expanded trig scales, and over-range extensions of basic scales.
These new rules are still FACTORY BOXED with English manuals!, the one shown is an unwrapped rule outside the box. An excellent pocket rule, the equal or better of K+E's Deci-lon, in a more compact format, with multi-line cursor. Exceptionally easy to read, even for old guys like me. All scales are self documenting on the right hand side. These are the first and only boxed, complete sets I have ever seen for this rule, when they are gone, that's it. (RH)

Aristo Studio 868

6"/5" Aristo Studio Pocket Slide Rules
New, unboxed, high end log log format rule, with new Sphere made cushion casem and original inspection certificate. Has a slightly magnifying 6 line cursor, CF/C and B/C scale yellow color stripes. Self-documenting, two-color scales, including folded, log log, P (pythagorean) and decimal trig scales.
Despite the high scale density, and small size, the scales are very readable and finely divided. This is one of Aristo's most advanced pocket rules, and is beautifully designed and built. A wonderful compact log log plastic body pocket rule, very seldom seen in North America, and extremely powerful. Susan designed the lovely velcro-flap case, made in a brown suede-like outer finish, and soft fluffy interior, excellent protection for these rules! We got these bulk packed, with no cases from Germany, so it took a while to come up with a good solution.
 We have a downloadable (zipped-adobe acrobat file) English Studio/Studiolog factory manual HERE

Body is adjustable at the back for correct action. Still aligns, looks and works great, how many computers made 80 years ago could ever say that? Pictures ARE the exact set for sale.

The back has reference data, and the slide reverse has trig scales. The cursor is a metal framed celluloid window. Both edges have cm scale rulers, one aligned at the end of the rule, and one offset. Still works perfectly, see if your computer can still do that in 2080 or thereabouts.

White "Ivorite" construction, with engraved black and red scales that include directional tilt for inverse scales. Includes original K&E embossed dark green (sorry, looks black in the pictures) leather clip case in good condition. A real powerhouse duplex rule from K+E in a convenient pocket format. The set includes a clip case and rule. The rule offered IS NOT the exact one pictured, but looks the same.
This rule works the same as the earlier and justly famous full sized 4081-3 and 4181-3 rules, but in pocket size. A very nice find, and an outstanding pocket rule, certainly the most desirable and requested K+E pocket model, and my personal preference for pocket rules from K+E.

Beautiful over-sized pocket bamboo rule with 3 line glass cursor (for circle area) and 2-part classic box case in NIB/New condition.
Has 6 inch side ruler, slide reverse has S, L and T scales and dual rear cursor windows, over-range scale extensions on ABCD, Dynamo/Motor efficiency and Voltage drop scales, and side K scale with drop-down cursor extension.
