Borge Mogensen or other? Mystery oak chairs... Help please.  

You are right about the link between SKM and Sor

Drpoulet: that is impressive detective work.

Sor

Thanks DrPoulet. I had also found that lauritz link, plus a couple others... Just nothing about designer listed. Appreciate the insight into the SKM...and the tip to look into Bruno Hansen.

And Leif - the craftsmanship on these chairs is definitely immediately recognizable.

Thanks to you both again for weighing in!

I think these chairs are probably from the late 1970s. That would limit the array of usual suspects to consider for designer.

IMO those are really good looking arm chairs....
