Heavy Brass Boat Light, Swedish, Marinarmatur

I think this thing used to live on a boat/ship, can’t remember where I got it but I remember making it work with a standard bulb as one of many of my DIY projects. Cast brass body, caged acrylic dome, wingnut clamps, and it's stamped MARINARMATUR SWEDEN on the junction box. Works placed an LED bulb to show it works but an Edison bulb would look great in this. Heavy-duty black cloth-covered cord attached. No on/off switch. Size: 10” in across, 13” in high 16” lbs. Some scratches on the acrylic. Needs a cleaning. Pickup in Bay Ridge, Brooklyn.
