Slide Charts and Letter relating to the Use of Bronze

<< >>
Usage conditions apply
Slide charts were sometimes prepared for companies that distributed other technical information. In 1941, E. J. Diebolt, sales manager for bronze manufacturer Sumet Corporation of Buffalo, New York, sent out this letter, which enclosed seven small graphs giving safe loads and speads for rubbing its high leaded bronze castings. The company also distributed a slide chart relating to leaded bronze (see 1988.3076.04).
