Anyone who collects or studies 19th century machine tools and machinist's tools will be delighted with the three catalogs that are reprinted in this valuable book. They include the 1868 catalog, the first offered by the newly formed Brown & Sharpe Manufacturing Co. and also the first to offer products from its related company, Darling, Brown & Sharpe. The next catalog, issued in 1887, contains a much larger range of products, reflecting the company's rapid expansion. The last catalog, issued in 1899, is dedicated to machinist's tools only. No collector or industrial historian should be without this collection, unless, of course, he is fortunate enough to own the originals.
