Daum Nancy Lamp or knock off?

This lamp is massive, like 2ft tall. It has been drilled for a wire near the bottom on the side (not very professional looking). There are chips around the edges of the shade and base. I think it might have originally been an oil lamp. It doesn't have a cut or polished pontil. It has a small hole which appears to have been formed by a mold or iron rod being pushed in. Any thoughts are greatly appreciated.

 

As a fabricator I find that a pretty cheesy bracket to hold the socket and shade in place.
Looks like it's been overtightened in the past to chip the top of the vase, or whatever it is.
The more you tighten that thin stamped sheet metal bracket the more it will bend.
I think it's a marriage to that vase...or whatever that is.
If it were a quality piece it would fit in a collar over the 'vase' I should think.
It also appears that the shade would be heavier than the 'vase' and so it would be very top heavy and asking for a smashing.
My 3 cents.

 

Not old either, from the look of it. Or French. My money's on a Chinese copy. If you like yellow and orange it's pretty, and would be great if the base lights too.

 

Emile Galle style Art Nouveau knockoff

 

Agree with the others ..... Modern.
