Nautical Oil Lamp Identification

I am trying to identify my oil lamp. The lamp is from an estate in the Northeast and was said to have been used on a ship in the late 1800’s - early 1900’s, and thought to probably be a whale oil lamp. The lamp is approximately 20 inches tall, and 3” diameter (at glass chimney). The glass chimney is very ‘wavy’. There are no identifying marks on the lamp that I can find, and the lamp does not have a wick winder.
