Wegner CH23  

They are real.
I lot of Wegner designs from different manufacturers left the factory unmarked.

Real!
Lucky you!
I've rewoven a bunch of olds CH23s and I don't remember any markings other than penciled letters or numbers.

Thanks for the input. I had a ch23 at one time with a Carl Hansen & Son burned stamp. These looked identical and the craftsman ship is the same. So I was guessing they were originals also. However, all four need new seats. Let the hand cramps begin!

88 Stamp
I bought a Wegner CH25 not long ago and it is not marked except for a stamped in 88.
At the time I asked for advice on this forum and several replies confirmed that I got a real Wegner chair.
I also sent an email to Carl Hansen & Son with pictures of my chair. The folks at Carl Hansen & Son further confirmed the replies I got on the forum stating that in the early years a lot of Wegner pieces were unmarked expect for a stamped in number. Based on my pictures they estimated that my chair is between 40-50 years old. I wouldn't be surprised if your chairs fall into the same age range as well.

I just picked up one of these from a local thrift store ($14.00) not a bad score but mine has the foil sticker on the inside. one thing i noticed is you said yours has an oak backrest? the one i got has a teak backrest and the rest of the chair is oak, now that i think of it I have only seen the oak and teak combo on this chair. did they make a variant that was all oak during the early years of production?
s.c.

CH23
Hi there,
I just restored 16 of these chairs for an importer of Danish furniture ...and I can tell you they come in all oak and oak frame with teak back. Hope that helps.
Cheers.

I have a CH29
with the 88 impression stamp as well.
