This is a desirable brass lens. I do not know the coverage but it should be at least 8x10. It has a beautiful circular aperture. It come on a board with a Packard air shutter. The glass is in beautiful condition for its age with no haze not fungus. There is slight separation toward the rear but this would be covered if you stop down at all.
