Perkins & House non-explosive safety oil lamp in brass, marked with the patent stamp PAT'D DEC. 11. 1866 and NOV. 24. This antique lamp is consistent with late 19th-century American manufacture and the classic safety-lamp form sought by collectors.

• Brass construction with a handled body, perforated burner collar, and filling cap present.
• Marked on the top with PAT'D DEC. 11. 1866 and NOV. 24, with the remaining date characters partially visible.
• Identified as a Perkins & House Non-Explosive Safety Lamp by the visible stamp and form.
• Wick material is visible at the top opening; burner assembly is present.
• Surface shows visible patina, tarnish, scratches, and general age wear.
• Underside shows verdigris/corrosion and wear along the base edge.

Made for oil lighting, this type of lamp would have been used as a safer portable light source. Today it displays well as an antique brass lamp, shelf piece, or study object for early lighting collectors.
