I feel like those sellers on American Pickers who drag their feet selling their favorite items, but I guess it is time. I purchased the chair about 8 years ago. I made an oak seat similar to a refurbished one I saw in Aspen, and painted the metal as original as I could match. It has been sitting in my garage all this time since I have no where to hang it. $300 - you pick up.
I also have a Borvig Quad chair (no slats on the seats) if anyone is interested.
