Description
This is a large Robervahl balance with the number 1148 embossed, twice, on the cast iron frame, and “TROEMNER PHILADELPHIA” inscribed in the center of the large flat copper pans. It was probably made in 1905, when the federal Assay Office in Denver became the Denver branch of the U.S. Mint.
