This pair of US Naval Big Eye Binoculars was made by Kollmorgen Optical of Northampton, Massachusetts. Kollmorgen has been making optics for the US Navy since 1916, when they were asked to design, build and install the first workable periscope aboard the first U.S. submarine.
Aboard ship these would have been mounted on a railing just off the bridge. This pair is now mounted on an earlier, circa 1940's, wood and metal tripod marked Professional Junior, Camera Equipment Co., NY Pat. No: 2818910. Camera Equipment Co. is known to have made tripods for the US Military during this period.
Optics are excellent and all parts are present and working including the forehead rest and lens shades, not pictured online. The original manufacturers label was removed at some point; pictured below is a plate from an identical pair. The binoculars are marked US on the right lens, also marked outlet.
