Slide Rules For Sale

The following rules are in search of good homes. “Following the Rules” is not a business; but once in a while a collector comes across a cache of items that need to be preserved and passed on to others. The majority of the items shown here were “rescued” (bargain price) from the bookstore at Penn State University nearly 50 years ago as the store made room for the new electronic calculators. They came into my possession recently through the original buyers. The slide rules, highlighted below, are available for purchase via PayPal. All proceeds from the sale of these slide rules will go toward keeping this web site alive, along with its upkeep and enhancement.

The slide rules are for sale “as found”, and all sales are final. Generally speaking, I found that the boxes may be scuffed from years of shuffling between shelves, but the contents are in very good shape.

Priced to sell, shipping within the United States is included. Requests for shipping to locations outside the U.S. can be discussed separately (email me). Any questions or concerns about a possible item must be communicated to me via email prior to purchase. Some images below may be representative only.

Thanks for looking, and for your readership and support of Following the Rules!

Learn to Use the Slide Rule

Get started learning about slide rules and how to use them with this fantastic starter set! The Pickett 120 has the most basic scales and is one-sided for easy use. Next is the Post (Hemmi) 1445, a popular intermediate simplex bamboo slide rule with 10 scales, a plastic carrying case with holes for inclusion in standard 3- or 5-ring binder, and Post’s 68-page instruction manual with examples geared toward self-instruction. These general instructions can be used for all three slide rules being offered. The Sterling 587 (labeled as 687 on the package) is a pocket-sized slide rule with basic scales.

Four Pickett Beginners

This starter set is Pickett all-the-way! It consists of Pickett’s plastic beginner’s slide rules Models 120C-T, 140C-T, and 140-ES. The Microline 120 Trig Trainer slide rule has 9 scales and comes in a white finish. The 140 Microline Log Log slide rule, also in white, has 22 scales. Both models are in their original shrink-wrapped packaging. The Eye-Saver yellow version (nice!) of the 140 comes in a fancier case, has lengthier instructions, and a box rather than plastic-wrapped packaging. Also provided is a separate 120C-T whose packaging has been slightly compromised – thus, you can immediately take it out for a slide right away and compare it directly with the 140-ES!

Collection Starter Set

Start your slide rule collection with a variety of popular rules. Included is the Post (Hemmi) 1445, a popular intermediate simplex bamboo slide rule with 10 scales, a plastic carrying case with holes for inclusion in standard 3- or 5-ring binder, and Post’s 68-page instruction manual with examples geared toward self-instruction. The Pickett Microline 140C-T Log Log slide rule, white finish, with 22 scales, was a popular plastic rule for math, science, and engineering students. The shrink-wrap packaging on these rules is slightly compromised – so don’t be afraid to take it out and use it! Also in the group is a Sterling 587 pocket rule in its original 1968 packaging (labeled “687”) for the on-the-go slide rule enthusiast. My 587 got me through my sophomore High School chemistry class! And finally, we include an all-metal Pickett N500-ES: The Hi-Log Speed rule, with 22 scales, was standard in technical schools during the 1960s and 70s. Comes in its original packaging.

These are great slide rules for learning how to use all the standard scales, with well written user’s manuals included. Makes for the start of a solid slide rule collection.

Teledyne Post	Versalog II	$75	1	In original sealed bag, the slide rule has date code WF (1972). However, the box has been very roughed up over time.

This famous bamboo slide rule made by Hemmi for Frederick Post/Teledyne Post comes with the 194-page Versalog II book (1970), late edition cover – very good condition.

Budenholzer, of the Mechanical Engineering Department, and B.A. Fisher of the Electrical Engineering Department, Illinois Institute of Technology.

Lafayette	99-7102 Vectorlog	$40	1	Bamboo vector hyperbolic slide rule made by Relay-Ricoh for Lafayette. Model number F-686 was also used for this rule, in early 1960s. This item appears to be from about 1966, though I have not found a date code on the rule. Brown leather case, strap is torn (could be re-sewn). No original packaging. Great scale set for the advanced user. `Tr1 Tr2 P’ P [ Q ST Sr Stheta C ] D LL01 LL02 LL03` `Sh1 Sh2 DF A [ B CF Th CI C _ LL1’ ] D LL3 LL2 db`
