OK,, so that explains that symbol !! Very odd that it looked exactly like the 1960`s peace symbol and since the lamp is from the same era you can see why I asked about it !! There is no artist by that name that I could find !! And if there was, the name would be very close to the artwork on the outside,, not hidden inside !! Name recognition is how an artist makes money so they want people to see the signature !!
Most likely the name is someone who owned the lamp before you !! That was not uncommon back then to have your name on your posessions !!
The movie “Gone with he Wind” was made in 1939 and subsequent re-playing of the movie on TV marked the interest in this style lamp even though they have been made and used for 100 years or more !! Keep in mind that in that time we only had 4 or 5 TV channels so a feature movie was a big deal back then !!
Another odd thing about the era was that little girl pics were a popular art form !! Have yet to figure that out !!

You can look through a few of these to see what I mean !!
So,, back to your lamp,, I doubt that it ever was an oil lamp although it probably did have a chimney !! The chimney was usually the first thing broken on these !! Most used a low wattage small bulb !! It was made mid century,,late 40`s to 1960`s !! If you look on ebay you will find hundreds of different styles !! All lamps are basically made by three mfrs,,one would be the glass,,the second would be the base which is a foundry product and third are the electrical components !! Most distributors just assemble the parts, and add their own labels !!
Hope I have not totally confused you !! And it really ticks me off that someone who is supposed to know lamps and lighting has so little knowledge about the subject !! Such as the person at the Q&A !!
