were there ever white Platner chairs in production?  

Ok.

Please remove the spot light from the inside of your lovely table. Platner would just die.

They gotta be original Knoll Platner.

It is theoretically possible that they were custom ordered white,

But I doubt that. More likely they were either professionally powder coated or spray enameled to accommodate a new decorative approach or to hide the pitting and rust.

One of my tables was painted black.

And no.

The finishes were polished nickel and yummy bronze. No white.

No,

i shall heed your advice

Auntie Dear.

Thanks, I do believe them to be authentic. I actually scratched the paint a bit and it seemed that there is bronze underneath, or could it be just the base coat.

Anyways, there is quite a bit of restoring to be done, figuring out how to get the fiberglass mold and the right fabric.

Thanks to all for your input!
