The Last Thing that You Acquired #29  

No, that looks like teak up...
No, that looks like teak up close. It is just dark. Maybe they used a lot of (exterior) teak oil on them, and they are covered in a thick layer of darkening teak oil?
As to the era of manufacture, some time in the early 70s Møller subtly, but significantly changed the shape of the 71 and 55 chairs (probably other too). The story I've read is that the factory burn down, so they got all new tooling. Anyway, in the earlier medallion mark era, looking at the front of the 71, there is a bit more curve as the legs merge into the backrest.
In that era Møller seems to have been less constant about affixing the medallions, so yours may not be marked.
If they do happen to have the later stamped mark, I am entirely wrong. But I don't think so. I look at both eras of these chairs all the time, so I've gotten to be able to spot the difference.

second ES 102
intermediate swivel arm chair, with chrome base and green hopsack by Alexander Girard is in the house. Just cleaned and drying in the sun.

Nice
That's a beauty. Don't leave it in the sun for too long....

Very nice
What did you use to polish the aluminum?

it`s back inside
@ woddywood it`s nearly dry now and back inside again, the sun dit a good job.
@ M_Dennis87 it`s a chromed base in very good condition, just clean it with a moist cloth.

hoopsie,
I've had lots of teak that dark. I like it! It's very rich looking.
I don't try to lighten it but cleaning the surface grime off will brighten it up. I use to use Murphy's Oil Soap (straight, undiluted) but it really dries the wood out. Now I just used oil and steel wool.
Be careful not to scrub too hard in any one spot or you could end up with a lighter area that will be hard to blend with the rest.

Tks Spanky, I think you are...
Tks Spanky, I think you are too late as I put a tiny bit of stripper on a small area and sanded vigorously and as you commented that spot became quite lighter lol. Anyways I think I may sell them and keep my eyes peeled for another set...hopefully

Hi Spanky, how would you...
Hi Spanky, how would you repair some lifted veneer from the back rest, also the "dog bite" on the chair legs ( see earlier pic) would you try to repair with wood filler or just a light sanding and leave as is. Tks again for the guidance

Sorry,
i've never repaired veneer. I don't have the skills.

... I was being an ass.

Re: veneer repair: why don't ...
Re: veneer repair: why don't you start a new thread with a photo of the veneer problem. The question is sort of outside the scope of this thread, and it is getting very long.

First time posting here....
First time posting here. Been a good month thrifting. Have found some othrr stuff as well that i will post up but i will start with this. I found these today at my local goodwill.
Its a Brass koch and lowy adjustable reading light. 7.99$
And 31 peices of a Georg Jensen prism stainless set. 3 types of spoons and 2 types of knives. But no forks 🙁 was only 15$! I was digging through the bins of China stainless finding all that they had of this great danish set. Maybe sell some of them to make a complete 6 person set
