Are these butchered Nelson pieces?  

Either they're very early...
Either they're very early Nelson or they're not at all. But the lack of encasement down the sides along with the two columns of hardware are certainly the big question marks. Indeed azure, we do need an expert... PEGBOARD, WHERE ARE YOU!?!?

and no ive not been drinking:(

.
custom work was done on this line but thats usually finish variants/knob requests not likely the form...one thing in this design the drawers are a dream...soooo smooth.

IMY MIND WAS BLOWN
From him:
"I did not drill holes in the set to accommodate the new hardware. I'm
attaching a photo of the original hardware so you can view it. I'm not sure
what type of metal they're made out of. It seems to have been painted gold
though. There are 16 pulls, 4 of the pulls have darkened with age; those
pieces were originally on the vanity, so I'm not sure if that had something
to do with the tarnish effect."
Here is the photo of the knob. First of all, it looks insane. Secondly, it appears to be a bad photoshop job.

Holy shite...
Looks like someone spray painted a funnel cake.

I think Im going to have a drink or few...my eyes ..my eyes...

In other words, I think this ...
In other words, I think this is a joke. It's a sloppy photoshop job.

Pulls?
How are you supposed to grip that thing? I think I would break my nails trying to open a drawer with those pulls anyway.

I am so confused. Why would...
I am so confused. Why would someone post this, acting like they don't know what it is. Then, even though the piece has the wrong knobs, photoshop in some crazy knobs in as the original? Can't figure...

Why shouldn't the seller act as if they don't know what is---
since nobody here seems to know either, it seems completely plausible.
The gordian-knot drawer pull photo doesn't even make sense if Photoshopped: the heavy black shadow is longer on the sides than the middle. (Taco shaped? I'm not even sure how you'd achieve such a shadow effect, in Photoshop.)

I don't get it...
maybe...
I don't get it...
maybe I'm blind, but how can you tell it was photoshopped? To me it just looks like he laid the 'crazy' handle on top of one of the pieces. What tells you it was photoshopped?

A flash
is capable of creating some highly "unnatural" effects.

I really dont think the ad,intentionaly spurious.I cant relate the loops to the furniture form even if unpainted, this, with the restrained hairpin matte alumi? legs.A picture can inspire a thousand words/questions.

I'm not sayin' these loopy pulls are Nelson,
but, a pastiche of restrained design combined with fussy ornament isn't unheard of...
I'm always startled when I see Eva Zeisel pieces like the one below--

When the Hallcraft "Tomorrow's Classic" dinnerware
by Eva Zeisel was being issued, Hall asked Zeisel to come up with patterns, in addition to the all-white. Although Zeisel did not actually design most of the patterns selected, she was not against the concept. She got her Pratt Institute students to design the patterns.
Her philosophy was "When in doubt, buy white".
It's interesting that the fantasy and a few other patterns are more collectable these days than the all-white.
