- Sumet Corporation
- Description
- This paper slide chart has a blue-gray envelope that includes a sliding chart printed in black on white. It served as an advertisement for the leaded bronzes produced by Sumet Corporation of Buffalo, New York.
- A window on the front of the envelope reveals a column of the slide that lists the commercial designation of a Sumet product, and its chemical composition (mainly copper and lead, with varying amounts of tin, and some zinc, nickel and phosphorus). Also listed for the product are such physical properties as tensile strength, elongation, Brinnell hardness, static load, and weight (in pounds per cubic inch). A window on the back shows a listing on the slide of the general applications of the same bronze.
- A mark on the front reads: Technical Data (/) for LEADED BRONZE. A mark on the back reads: SUMET CORP., BUFFALO, N. Y. A copyright sign precedes the company name.
- Bronzes with commercial designation from SM-4 through SM-18 were being produced by Sumet Corporation from at least 1931 to at least 1937. Hence the rough date of 1935 assigned to the object.
