Opera Glasses

Description
The objective lenses are about 29 mm diameter. The frame is black metal, as are the eyecups and the center wheel that adjusts the focus. The barrels are covered with a 3-dimensional leaf pattern. The words “PAT’D. OCT. 19 1886” onto each barrel refers to U.S. Patent 351125 describing a “Process of manufacturing colored relief impressions on sheet metal” issued to Friedman Priester and Otto Weidemann, both of Berlin.
