20 Inch Slide Rules, Various Makers

Many slide rule makers produced long, 20 inch versions of some of their models. While not as convenient to carry as the standard 10 inch rules, the longer rules offered greater accuracy.

I have many varieties of 20 inch slide rules, which make great collectables, gifts, or user rules. A few examples are shown below. If you are interested, please click on the Questions and Wants button at the top of the page and ask for details.

Chairman Mao, Chinese Slide Rule, Very Advanced Model, New in Box, with Self-Documenting Scales and Chinese Manual

This new-in-box, Chinese slide rule was made during the Cultural Revolution and is labeled, in Chinese, "Worker, Peasant, and Soldier." The text on the box also says, "Double-Sided Rule," "Auxiliary Feature: For Radio Electricians," and "Tian Jin Slide Rules "

The box further features a saying of Chairman Mao, which translates as: "We, the Chinese people, have the gumption of fighting our enemy to the bitter end; the determination to restore the faded glory with our own two hands; the ability to gain our standing amongst the rest of the peoples of the world."

This is not only a fine, heavy-duty, 23-scale rule with metal end braces, but it is also a piece of history, representing the post WWII, Chairman Mao era in China.

The rule includes a manual in Chinese. In addition, the scales on the rule are self-documenting (they are labeled not only by name, but also by the actual mathematical function they represent). Therefore, almost any good English slide rule manual can be used to learn how to use the scales.

The cases vary in color, but the rules are the same.

Here is a chance to own a new, 40-year-old piece of history, even as China evolves into a world economic power.
