Is this a Herman Miller Shell Chair?
I'm trying to verify the make of this chair. I know very little about these chairs and have had a hard time finding any information to help me determine the make on my own.
The only marks I can find on it is 3 dots center/bottom of the chair (on another thread someone was talking about these being a clue) and a stamped "AX".
Since I can't find any info to help me I was hoping there is some tribal knowledge that can help.
