Balance

Description
This is a Projectomatic precision balance of the sort that Christian Becker introduced in the early 1950s. The case is aluminum, with glass sides and top, and drawer in the bottom. The beam is aluminum; the knife edges are agate; the pans are stainless steel. The inscription on the handle reads “Christian Becker.” Another reads”Christian Becker / Clifton, New Jersey / Made in U.S.A. Serial no.
