The Finn Juhl Rocking Chair  

.
For what reason are you certain it's not made by France & Son?

Hi Onno.
The way the chair is construction looks very atypical of France & Son pieces.
The joinery and shaping of the timber looks off and lacks finesse.
The visible screws are not the standard hex key bolts used by France & Son.
The sculpted ends to the armrests differ in size to a Model 133 Spadestolen.
There is a visible screw holding the backrest to the back of the armrests.
Iv'e never seen this design listed in any France & Son catalogue.
Whenever I have asked anyone selling this design if it has a France & Son tag the answer has always been no.

Okay, some arguments seem to be reasonable, I'll try to find out some more background infos.

I think these were made by Pastoe
don't know if they resourced the design from Juhl.
Chairs were often not labeled or be it with a sticker,
wich easily falls off.

It's presumably based on...
It's presumably based on this FJ non-rocker (below), in which tapered dowels are used for the vertical parts of the frames, rather than the squared-off planks you see in the rocker. Though maybe the planks are necessary in the rocker because they are bigger and can better bear the stresses of rocking?

Pastoe: easy chair version
I think bj is very likely correct here. Attached are photos of the easy chair version of this rocker, with a pastoe label. It is current for sale on palisander.nl, so I won't post the link.
Not 100% conclusive, but very strongly suggestive.

I recently bought 6 of these spade chairs (5 ordinary and 1 rocker) in Denmark, where they had been placed in a in holiday home. No marks or stickers, but I wonder if they were bought in Holland and taken back to Denmark.
Maybe Pastoe sold furniture in Denmark - or maybe there was a danish license on this model as well.....

Made by M Nissen

Oooh that's my lounge chair! Where did you find that Leif? My chair is marked with the M. Nissen sticker. I put it up here to ID last year. It's very comfortable and lovely to look at!

On the Internet. Some blog somewhere. Has a number of old Danish furniture ads. Loppefund something in the URL.
I think it definitely rules out any question of Finn Juhl's involvement (and it was already a non question in my mind).

Yep I agree, and the differences become even more obvious when you see and feel both.

The lounge chair is Model 65 and the rocker is Model 66 made at M. Nissen factory in the Danish city of Horsens.
No specific designer is listed.
