A good sturdy copper and brass Meteorite Anchor light by the makers Harvie.

Clear fresnel lens, protective vertical brass bars, swimg handle to top and base, hinged lid with safety chain and burner and clear fluted shade present inside. This fluted shade wouldn't have been the original but it does the job.
