could that be early egon eiermann?  

Maybe you @Barry/Amsterdam! You seem to have pretty good knowledge about Eiermann work. I would appreciate any Infos about who commited that chair!
Thanks a lot.

Is anyone out there who know sth about Wilde+Spieth early production. I got a confirmation about the base. It is production of W+S from around 1952. But noone take a comment if that could be a leather upholstered SE 69 from Eiermann.
Any feedback?

Hi,
Wilde + Spieth is still producing Eiermann chairs so you can ask them for more information:
http://www.wilde-spieth.de

I did ask. As I mentioned in last post they confirmed that base is made by them. They unfortunately didnt help me with any archive pictures. They said that "Eiermann was not really doing the uphostery chairs since he like how they look without cover"
I know though that for some time there was produced a chair SE 69 with leather uphostery. just cannot find much material about it. And noone seem to know much about it...
:/

If the base is confirmed, what is the question? It looks pretty cool. Here is another example picked out of the Googler, does yours look the same as this one when viewed at the same angle?
