Hans Wegner CH23 Chair. What To Look For?  

Hello,

I'm interested in purchasing a vintage Hans Wegner CH23 Chair. I am not an expert, however, and I want to know what to look for. Here are several photos of a teak & oak chair that has been refinished with a new paper chord seat. Do you see anything wrong with this chair in these photos? I live in NYC and went to the Carl Hansen store to check out the new CH23 chair. Something was off about them but I can't tell you why. I believe vintage is the way to go but I don't want to make a mistake. Though the CH23 isn't as valuable as a Cow Horn chair, is there a version of the CH23 more valuable and sought after than the next? Your help is appreciated. Thank you.
