Keuffel & Esser 4013 Thacher Cylindrical Slide Rule Exhibit Label

Usage conditions apply
This cardboard describes a Thacher cylindrical slide rule with a magnifying glass that was manufactured and sold by Keuffel & Esser of New York in the early 20th century as model 4013. (In the late 19th century, K&E numbered the instrument as 1741.) It apparently was used as an exhibit label around 1966 at the Museum of Science & Industry in Chicago, the previous owner of the related instrument.
