Perko lamps like these were either steel or brass. I have only ever found one other set that were chromed and they had been electrified. These are not. They are totally original to burn lamp oil. They date from 1950. One is a port bow running light and one is a starboard light with red and green Fresnel lens according to light.
Perko Company is the manufacturer and these lights were made 1950-1959. Mid-century collectable.
They have been in my possession for over 50 years and have been stored in the house all those years. Height is 10.5 inches. 5 inches wide and five inches deep.
Any shadings in photos is glare from sun. The chrome is excellent with no rust and super shiny. Insides are clean. There is no damage of any kind.
I had them hung from the ceiling in my living room. Time to start parting with treasures. You could use them on your yacht, in your home or in a business such as a bar or club.
