A pair of Dutch Copper port and starboard oil lamps made by Den Haan of Rotterdam. The copper lights with brass accents have "STUURBOORD" and "BAKBOORD" labels on the top, red & green Fresnel lenses, burners, shades, and glass bulbs inside. They stand 9.5 inches tall with approximate base measurements of 5" by 5". They show signs of minor wear and tear (see pictures) but have full functionality and no major dents or scratches.
