Eames Tandem Shell Airport Style Bench

Hi,

We were given these by a family member a few years ago. Sat them in an extra room as decor and never used them. It's really unique and I wish I could keep it but I don't have room in the new apartment. I am told they are Herman Miller by an unreliable source lol.  It is in great condition.  Any info and estimated appraisals are appreciated. I didn't realize they may be worth money until I accidentally came across one online. I then researched them and found them sold from $$300- 2000.  

Thanks a lot !!
