Weighs an impressive 4 lbs, solid brass and copper lamp. I got it from a man who dismantled a wooden yacht that was purportedly once owned by actor Errol Flynn. Extremely rare lamp in original condition except for power cord added. The shade rotates and it is designed for a medium base tubular bulb. Toggle switch works but a little finicky and may need cleaning or replacement. Not a cheap Chinese replica. No markings to indicate maker, cannot find another one like it online.
