Need Help Identifying Oil Lamp External Filler Tube

I am looking for help in identifying this lamp. Bought it at an estate sale of a 95 year old. It has an exterior filler tube, and a lever on the side that raises a metal shaft over the wick to extinguish the flame I believe. On the knob, it is dated Jan. 16, 83 and Feb. ??, 73. It has a marble base. It measure 12" tall without the chimney. Any information that you can give me will be appreciated.

Thanks,

Denny
