Helikon Chairs

I don't know much about these chairs at all & would love to know anything. I found a tag that says "Helikon", but haven't found any other markings to help identify them.
I acquired them through a trade & the only info. I got from the trader was that they are "Helikon" chairs that are roughly 25+ years old.

I just love the way they look & their cool lines.

Does anyone know anything about Helikon? What they made? If they're still in business? And does anyone know anything about these chairs?

Any help would be greatly appreciated!
Thank you!

Have no interest in selling them. Not listed for sale anywhere. Just interesting chairs, that are mine, & are staying mine, & that I'd like to know more about.)
