Object Details

Description

This 1-3/4" cylindrical metal case holds three pencil leads and three needle points for dividers. Leads and needle points were needed for drawing compasses and mechanical pencils used in engineering drawing; one often found a case like this in a set of drafting instruments. William J. Ellenberger (1908–2008) owned these objects. For his biography, see 1981.0933.25.
