Original Perkins (Perko) Marine Lamp & Hardware Corporation, Brooklyn, New York, oil lantern with its brass ring hanger... in over-all very nice condition, with the great patina of age throughout. It indicates it is "Patented" but I do not see the year. It has no damage, the green and red lenses are solid and sound and no dents or breaks. It measures side to side, wide open... 15" wide. It is 9-1/2" high or, with its ring, 11" high. Closed and compact, it is 5-3/4" high. It mirror is nice, clear and perfectly intact.
