Perko All Brass Towing masthead Light With Amber-Colored Fresnel Lens

A mid-20th-century all-brass PERKO masthead towing light. Features a 225 degree plexiglas amber-colored Fresnel lens. Four mounting logs and a top swivel ring. Originally produced as an electric light, we've replaced the interior light and replaced it with new. The light switch is located on the lamp cord. There is an approximate 1-inch hole drilled through the back for the electrical cord to pass through, plus two small holes for attachment. The light fixture is attached to the original bayonet-twist type removable bottom plate that fits into a 5-inch diameter hole. Expected wear to the brass fixture and lens from actual use at sea. Engraved PERKO and pattern number, H-6-71, on the bottom of the light back. Measures 11 inches tall with a 7 X 7 x 7-inch bottom. Weighs 8 pounds. A pretty rare PERKO navigation light!
