Rosewood dining chairs  

The shape
of the chairs has a similar look to some of Percival Lafer's design. And not unlike other Brazilian made mid century furniture.

I see where you are coming from,
but I'm not convinced that they're Brazilian. I think they're European; either Scandinavian or British.

I would guess british.
Didn't archie shine used legs like these on sideboards..?

Hi bj,
Good chance that they are British.
I have a fairly good knowledge of Archie Shine and I haven't seen anything that is similar enough. The sideboard legs would be round - these are more of an elliptical shape.

Just found the
Made in Denmark stamps whilst re-upholstering.

Found some on lauritz
Some of the same chairs sold on lauritz. Even the same turquoise upholstery. The seller claimed they are rosengren hansen for brande mobelindustri model 39. And further claimed literature to back it up: Mobilia nr. 104, marts 1964.
I can't speak for the accuracy of the identification. And brande model 39 by rosengren hansen tends to show photos of a different chair, which seems suspect.

That's brilliant.
Thank you very much, Leif.

They have never
been brande chairs and certainly not model 39.
I would at best attribute them to Danish inspired.
below are the real chairs:
Designed by Henry Rosengreen-Hansen
Produced by Brande Møbelindustri
Model 39,
Year of design 1963

Hi Simon,
I did further checks and noticed the same thing.
I also thought that they were British, however, when I was reupholstering the seats I found that they were all stamped Made in Denmark. The mystery continues...

I just noticed that this chair by Brande Mobelindustri
according to the attribution it was designed by Kofod-Larsen. I must say, the frame does look very similar, but there are also quite a few differences. It could be a lead though?
