Help identify these chairs  

Ib Kofod-Larsen 1960s Denmark Teak
Peruche

Thanks!! I also noticed a something that seems off to me but may be normal, let me know what you think. On one of the chairs the red Selig marker is a thick plastic and sits in a recessed rounde out part of the chair, on the other it is just a flat peel off type sticker and there's no recessed hole to indicate that there was once plastic marker. Is this common?

The OP's look a lot like stained beech. The seat foundation is stained beech, and the wood beside it, while it can't be seen clearly has such a close tone I suspect it is stained beech as well (Selig's saddle finish). It might be oiled walnut, maybe, but not teak.
The catalog image says it came in oiled walnut and rosewood. The wood options may have changed over the years, but I must say that I would like to see one of these in rosewood.
And the chairs on the riverbank are definitely oiled walnut, not teak, not saddle stained beech.

Never seen a Selig sticker before, but Selig did not always use the medallion either. Early chairs had a different seat frame, with cinch straps, and sometimes a block letter stamp behind the front stretcher.

I found it to be odd as well, but the chairs are identical. I was told these were teak, however THe person I purchased from was not a dealer and not very educated on the furniture. I recently oiled them myself with scan care teak oil, here a few close ups of different parts of the chair maybe you can help determine the type of wood used.

Interesting. I had never noticed that this Selig model catalog sheet called for a rosewood option. I don't believe I've ever come across a Selig Kofod Larsen rosewood chair. I've seen some KL rosewood pieces at Wright, but those were all by Christensen and Larsen.

To be honest, I have no idea what the difference is between a paper or medal Selig medallion. I have seen both over the years and would also be interested in finding out what the correct answer is. I have some theories but would rather hear or read facts.
Anybody else like to chime in on this subject......

Csilva: me either. I think it would look quite impressive in rosewood. I bet there are very few out there.
OP: that is oiled walnut.

Every Selig medallion I've seen was a recessed button, on the front right side of the seat frame, not placed over a wood joint, and not rotated with the cross off axis.
If you have a magnifying glass, take a look to see if the sticker graphics are solid color or made from tiny dots. Also, I can't tell from the photo if the circle and cross edges are silver or gray.

nice site you found there, Peruche. Seems like a very knowledgable fellow.

cdsilva,
Here is a picture of a Selig sticker on a chair I once owned.

Peruche: I don't follow, I get a feeling you are asking me a question, but I can't figure out what it is? Happy to answer, just help me with the question.

leif ericson,
I posted that link because I thought that it was similar to what you were saying about the early Ib Kofod-Larsen chairs having a different seat frame and cinch straps. I thought it was interesting that I had come about that site not to long ago and you happened to mention things that the site was describing.
Now that I have your attention.....
leif ericson,
Can you answer my question about the difference between the Selig paper sticker & red metal medallion.
Why does some Selig furniture have one or the other?
Thanks
