Rare (Vaseline Glass) Antique Hall Oil Lamp

This is a very uncommon, 19th century Hanging Oil Lamp that would have been hanging in a hallway or entry of a home. I am not sure of the maker as the glass is not marked, possibly 1880's Hobbs Brockunier "Dewdrop" or Fenton Hobnail?
The metal base pulls down as the glass raises up using a pulley system to expose the oil lamp inside for lighting or refilling the lamp with kerosene. The particular lamp was made using Uranium Yellow/Green glass AKA Vaseline glass, in an uncommon pattern. The glass ball is approximately 10" in diameter.
I purchased this lamp with a very old electric cord attached and chain (as seen #4) to hang from the ceiling but it was easily converted back to its original condition and the metal polished to its original luster.
The 1st photo was taken in a dark room with a blacklight shining on it.
The 2nd photo was taken with regular LED room lighting.
The 3rd photo was take in the same dark room using only the flash from my cell phone.
The 4th photo is how is looked when I purchased it.
