Description: PLEASE SEE ALL PHOTOS AND ASK SELLER ANY QUESTIONS This came from an ancestor’s estate (b.1893) who was a builder. All details are from what I find on the slide rule…it measures 11” long in the case. The tab has come unstitched from the case. The slide rule has markings…KEUFFEL & ESSER CO.N.Y. Pat June 5, 1900 N 4053-3. Numeral on end 294964. It is in good condition but some discoloration in 2 spots that seem like it had tape or something on it. The slide rule is perfect for those interested in the history of engineering and mathematics. It is ideal for use in schools, universities, and for personal use. The markings on the slide rule are clear and easy to read, and it is a great addition to any collection. The leather case also provides protection for the slide rule during transport and storage.
