Soren Hansen stools - authentic?  

Hi Collective Wisdom,

I'm thinking of picking up a set of what are advertised as Fritz Hansen dot stools - but the early Soren Hansen versions. Given that they don't have Fritz Hansen stamps, I'm obviously a bit leery, but if they are Soren Hansen (and supposedly the exposed screws are indicative of early stools) then it's possible that they wouldn't have the FH stamps.

I've included a couple of images. I think that the legs are the key, as the mounts and legs are pretty distinctive (and possible primitive?)

Thoughts?
