VTG Light Signal Nautical Battleship Waterproof Train? Navy? Orange Rare! Diver

This is a very interesting light. I have tried to research this and found no other signal similar to this. The bulb in the top lens is small to medium and has many fibers inside with a bluish purplish tint. This I think was used on the water or on a ship but also could be railroad or street signal? No idea if you have any info on this that would be great. This would be great for the signal collector. This signal is very heavy and well made. Thanks and
