Author Description

A complete black and white reproduction of the Keuffel & Esser Co. 1921 Catalog with a new introduction by Ross Bolton. This catalog is special in that it features a huge selection of surveying and engineering drawing tools (such as slide rules, transits, and planimeters) from the most collectible period, and it came out just after Keuffel & Esser bought out Young & Sons of Philadelphia, PA in 1918. The 1921 36th edition is a nice part of anyone's collection since it has many drawings of component parts to enable the collector to better repair their collectables It also has instruments with glass optics made by K&E (manufacturing started 1916), and many instruments not featured in the other earlier catalogs.
