Take A Classic
1928 Slide Rule Lesson
With K+E









Take a 1928 class with with K+E and learn how to operate a K+E 4058W slide rule. An incredible look back though time that still works perfectly today.

This supplemental K+E booklet, published and copyright in 1928 by K+E is a great practical explanation of how a rule works, and how to read and set scales. After 70 years, it's still an amazing and useful piece of information, and very useful. It is reproduced here exactly as it appeared in 1928. Just CLICK on the link to each page to see it.

Each double wide page is about 200K, the entire booklet is about 2.4Mb. It is worth the wait to see it. Use your browser RETURN to come back after each page, and you can print each one via your browser to make a booklet copy for review.

We believe this document is now in the public domain (over 70 years from the date of the corporate copyright date), and was free in any case, but if we are incorrect, please advise, and we will remove it immediately.




Our thanks to Don Harold and K+E for this other wonderful piece of slide rule history!

The LESSON will appear below shortly!
