Sterling Plastics
Founded by George and Mary Staab of Mountainside N.J., they purchased Acu-Rule Mfg. on June 25, 1968. Sterling operated in Mt. Olive for about a year and then moved the plant equipment to Union, New Jersey, then settling in Mountainside, New Jersey. Sterling Plastics was purchased and became a division of Borden Chemical in 1970. Slide rules were produced as late as 1972. Most models use the same mold, but vary at time by the color of the text or plastic slide or stock.

Note: this is the transition from 2 bridges holding the stator together to 5 bridges. Evidently the first design was not reliable and the Sterling engineers modified the standard tooling to strengthen the stock. This was not intirely foolproof, as is evident from the 684 below, which belonged to the ISRM Curator's father.

Mike Konshak, the ISRM Curator writes about his parent's slide rule: "Like most things Dad and Mom had, it was not elegant, always practical, and in this case is one of the least expensive out there. Yes, it's a Sterling 684 which many collectors wouldn't even give a second glance. Sometime along the way the plastic slide rule broke and rather than toss it away, Dad (or Mom) epoxied it back together and it was given a new life. Eat it up, wear it out, do with or do without. Les spent 20 years in the USAF retiring as a Senior Master Sergeant in 1959. He was an original founder of the The Retired Enlisted (Men's) Association (TREA) first charter in Colorado Springs, He spent 10 years working at Ampex Corp. in Colordao Springs and retired with a small pension. He and Susan (ne Garrard) spent their last years living in Tucson, Arizona Dad passed on in 2010 at age 93. Mom passed on in 2003 at 84. They are both buried at Fort Logan National Cemetary in Colorado. They had 4 children, 7 grandkids and as of 2011, 5 great grandchildren"

Donated by Ron Pierce of Littleton, Colorado
Ron Pearce describes the slide rule that belonged to his father, Finley Pearce: "He was a chemical engineer who worked primarily for Shell Chemical. The personal attachment for me is that as far as I know most of my siblings, including myself, literally cut our teeth on the slide rule case that held this slide rule. The case is gone, but the rule remains." "In another slide rule story, I recall being called to the president's office at Southern Pacific Transportation (railroad). The president was Denman McNear who was himself an engineer. I was a cost analyst at the time and used an HP financial calculator to perform my analysis. Mr, McNear would check our figures using his pocket slide rule which was about the same size as my father's slide rule."

Gifted by Norma Tanner of Libertyville, Illinois
Norma has been a participant of the ISRM Slide Rule Loaner Program. In addition, she had her own collection that she loaned out to students. This one is part of the collection sent to ISRM. Norma writes: "After teaching math and/or science for 24 years, I am now enjoying retired life. Having been educated at MIchigan State University during a time when using a slide rule was the only technology available for advanced calculations, I decided to create a unit of study for my students that would introduce them to the slide rule. My goals were for students to strengthen their ability to estimate and use scientific notation, as well as to discover the historic significance of the slide rule. While it was hard for them to put aside their electronic calculators, they were fascinated, engaged, and thrilled when they could multiply 2 x 3 and actually get 6 instead of 5.9. In the end my students were happy to be reunited with their calculators, but had a new appreciation for the value of estimating, scientific notation, and accuracy in measurement. Goals met! "
