Hans Olsen sofa  

I saw a gorgeous armchair a few weeks ago (first pic) in a mid century furniture shop in London that was attributed to Has Olsen, and have been trying to find out a bit more information about it online but to no avail.
Struggling to find out any detail on who manufactured it and when, and beginning to wonder how genuine the ID was.
I've seen one other place online that attributes the matching sofa to Olsen (pic 2 and 3) but was just wondering if anyone knew any more details about the set?
Don't think i'm going to bother with the dealer priced set (a bit out of my budget) but keen to keep an eye open for a bargain anywhere - especially as i love olsen's roundette dining set.
