- This tan, 36-page booklet is titled: Staedtler-Mars Instructions for Use, Modles [sic] No. 944 24 No. 945 24 Bamboo Slide Rule. The back cover is marked: Printed in Japan.
- The instructions define the scales; explain how to multiply and divide; solve problems of proportion; discuss squares and square roots; calculate cubes, cube roots, 3/2 power, and 2/3 power; explain logarithms; provide processes for trigonometric functions; discuss the P or Pythagorean scale; explain the LL scales; and define this rule's five gauge marks.
