* 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, 8am to 5pm, PST. We process VISA/MC orders immediately. You can also send your order by FAX at: (250) 769-4106.

* SHIPPING: Canadian ExpressPost (NOT regular mail, this is like US Global Priority/Courier) Rates: To USA destinations, shipping and packing minimum of $23 for any insured, trackable air shipment up to 1kg (typical delivery within 5 business days), Canadian destinations are typically $10-14 (delivery within 2-3 business days). It is also possible to ship uninsured, untracked, small packets (250g max.) for roughly $12-14 to the USA, but delivery delays can be up to 8 weeks according to the US Postal Service, and so we cannot recommend it. Virtually all of our shipment failures have been because of this method, so it should be used with caution. We have an extraordinarily good success rate (better than 99.9%) with ExpressPost, so we highly recommend it, especially for one-of-a-kind items. It is cheaper than couriers, trackable, more reliable, fully insured and goes almost everywhere.

Shipping/handling to Europe, Australia, South America and other overseas areas via Canada Post International ExpressPost air mail insured service or Canada Post International Air Service where ExpressPost is not offered is $51.00 for parcels up to 500 grams/1 pound. Shipping and packing via regular mail to these locales is $22.00 for parcels weighing up to 500 grams/1 pound. This service offers no guarantee, insurance or tracking and we then accept no liability for loss or damage. Transit times are unpredictable by this method.

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

We can also ship FedEx or UPS when time or weight is critical, and over-night FedEx P1 shipping is available. Note that our pick-up cut-off time is noon for FedEx. There is a packing charge for large equipment, see the FAQ for details. If we have your valid data on file, you can just click on the ORDER email link to place an order and indicate your approval to bill, and we will do the rest. If this is the first time you have dealt with us, you can phone (250) 769-1834 or FAX +1 (250) 769-4106 the billing info, or send it by the email link, as you prefer.


* We scoured the world looking for inexpensive slide rules for learners and classes, and came up with a large quantity to pick from.

MOST RULES CURRENTLY LISTED HERE ARE NEW !

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!
