* To make your life easier, and help you find exactly what you want, we have broken the on-line slide rule catalogs into smaller sections. Just CLICK on the icon of the rule type you are looking for at the left, to see the matching catalog. Large graphical catalogs are a bit SLOW, please give them time to load.

You can order anything here just by picking up the phone, and calling (250) 769-1834 during normal office hours, 8:30AM to 4:30PM PST, or FAX to (250) 769-4106. OR, Email your order to Susan CLICKHERE.

Shipping*SHIPPING: Preferred and Alternate Methods as of June 4, 2013, CLICK for FULL DETAILS ON OUR FAQ Page. Rates are now changing rapidy, often with little notice to us, so all the data has been transferred to the FAQ page for speedy updating.

* E-Mail Susan if you want a quote for shipping to other destinations, or for something heavy. Sorry, we can't safely send most individual small parts in a regular letter envelope, they get destroyed by the automated handling equipment. Sometimes we can ship very rugged parts in a small padded envelope by letter post. Ask Susan.

Please note that there are transaction fees with Paypal and wire transfer payments, the wire transfer fee is frankly horrifying.

We accept VISA/MC or international money order

* To answer your questions, YES, we completely clean and inspect all used rules, and do not offer any we feel are substandard. If there are any marks or detracting features, we clearly state them in the listing. Before shipment, we clean the rule faces and cursor, the slide guideways, align the body, and align the cursor. We also clean and polish the case, so that when you get your rule, it is as ready as possible for you to enjoy.

Our most requested K+E Rule, BACK IN STOCK!

6"/5" Pocket Slide Rule
K+E's famous Deci-lon 5 duplex rule, in the hard to find pocket format with an orange sewn leather clip case. The rule is in good+ condition, the case and one bracket have some wear marks as shown.

JUST ARRIVED!
5"/6" Pocket Mannheim Slide Rule

Beautiful Hughes-Owens miniature pocket bamboo rule with framed glass cursor and embossed leather slip case with flap. Very good condition sets with optional Hemmi manual!

Has inch scale side ruler, reversible slide with 3 additional scales. A very attractive and hard to find rule, this style is always in high demand (because of the light weight and good feel), but hard to locate in new condition.

Made by Hemmi in Japan, but sold as Hughes-Owens in Canada (POST in the USA). This is the same as the Post 1444. These were promotional sets for Imperial ESSO in Canada, and have that embossed on the front of the case (some green tarnish there becase I think the embossing foil was copper or brass), the rules are still in sealed bags. The optional book is an extraordianry Hemmi publication from January of 1957, and covers all their Mannheim style rules, and is well illustrated. It includes an additional illustrated catalog at the end. A bit of foxing on the covers is due to long storage. These rare books are available with the rules ONLY, sorry. The rule I examined closely has an FL date code, which is December of 1955, talk about an amazing find for a new factory sealed set!

A GREAT FIND!

6"/5" Duplex Log Log Pocket Slide Rule
New, but NO BOX and with Manual Reprint with very dark green embossed leather case, and English manual reprint. These have been in storage for along time, and the manuals (spanish) and boxes were deteriorated, you can have them if you request them, and we still have any left. We carefully cleaned and lubed these, now they are ready to go. This is the pocket companion to the full sized 2/83N sets. Price is by email quote only, we won't post it here becuase it only drives up the prices world-wide. A wonderful and highly advanced plastic body rule, very late production. With duplex many-line cursor, two color (red/black) scale markings, beige braces and pale green stripes on primary scales (both sides), and pale blue stripes on A/B scales (one side).

The Rule is self documenting on the right hand side for all scales. A very powerful and beautifully made log log pocket rule, equal to the K+E 4181-1 and Post versalog 1461, if not significantly better. Has pythagorean scale (P), CI, folded scales and dual square root (W1) and square root 10x (W2), and 8 log log scales! Plus, very unusual design of combined D/LL0 gives two scales in one.

Mint, very late rules, a more compact and lightweight version of the beautiful 2/83N, very attractive, with gripper extensions on the slide. It took us a long time to get more, so don't miss this chance to get a set. You can download the zipped english manual in two parts HERE and HERE.

Very similar to the popular POST 1441 pocket rule, has metal framed glass cursor, reversible slide with 3 additional scales, rear cursor window, 2 edge rulers and reference data.

Some box wear, with tape on ends and penned in model number. An outstanding and practical pocket rule, ideal as a gift. These were locked up (12 years!) for a surprise in our save-til-later-room, no more available when these are gone.

Walt's personal pick as the best starter pocket rule!
Nestler

5" Pocket Rietz Slide Rule
one of Nestler's nicest basic pocket rule, BRAND NEW late production rules, still cello wrapped, with factory English manual, and embossed leather case. Has green tinted slide and white body, 3 trig scales (S, T, ST) and extended basic scales, with a 3 line cursor and 5 inch edge ruler. Self-documenting on right hand side with red marked inverse CI scale. The pics seem to show the left side faded, but that's a lighting artifact, the rules are perfect, and evenly marked.

A great value starting pocket rule, with a great appearance thanks to the colored slide, and rare to find in MINT new boxed sets.

6"/5"Pocket Slide Rule
Ivorite, Log Log Duplex Decitrig (also known later as the 'Jet-Log', or in this pocket size, the 'Jet-Log Jr.') rule, with metal framed unbreakable cursor. White "Ivorite" construction, with engraved black and red scales that include directional tilt for inverse scales. Includes original K&E gold embossed orange leather clip case in excellent 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 both items in excellent condition, even better than pictured.

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.

This has blue and red scale markings with the early blue COS scale and adjustable metal end braces. The set includes the embossed leather clip case and rule, hard cover manuals are also available. Very Good condition, but note that the case is lighter in color than the photo shows, I couldn't get the color balance quite right and show the scale details.

A powerful but lightweight pocket duplex rule, this has 8 Log Log scales, split high resolution square root scales (R1/R2), folded and trig scales. A very attractive and hard to find rule, this style is always in high demand (because of the performance, light weight and clip case), but hard to locate in good condition and an unmarked case.

Made by Hemmi in Japan, this is an early production set with date code HH, from August 1957.
