Hi Bill, I had never opened the box so these pictures are of the arms out of the box for the first time. No yellowing on them. Also the model # of the seat is TGW2005. Technically you did ask first.I had asked about these arms earlier, but now wonder if they may have yellowed in the box. I know Doberman asked earlier and I don't want to cut him out. But I'd also be interested if they are not yellowed like the ones I have that are installed. Your picture looks exactly like my 2007 chair. You mentioned they have never been opened, if Doberman doesn't come back and they are not yellowed please let me know.
Thanks, I'll check the model number if there is one on my chair and get back to you.
