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.

Send email to syphersm at gmail.com to reserve your item. Payments are to be made via PayPal.


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