Kelsey Hayes, of Cleveland Ohio, made the body for a 6 x 30 for the U.S. military circa WWI, a little different that the standard model. They also made a prismatic rifle telescope for U.S. Marines at that time. A web search shows they were a large manufacturing concern. Does anyone know any details about this binocular or the company? ................
