After many months and still have not identified, I had decided to take Duckshot's advice and removed the lense. On the inside it has Ropp Glass written and Pittsburgh Lamp. They made lenses for Railroad and molded technical glass for demanding applications. " selenium red " glass, or ruby glass. It looks like the clear lense goes up to shine white and not red. The lenses show red through the lenses. I still do not know exactly what is was made for. This heavy box looks manufactured, not tin, so I think there should be others around. Any help would be appreciated. Bill
