Gastone Rinaldi Chrome Chair?  

Hi everybody.
I found this nice chrome chair at a local thrift store and picked it up. After some googling I found an identical chair for sale at etsy. https://www.etsy.com/no-en/listing/200043339/gastone-rinaldi-chrome-chair-1970s
My chair is unmarked but has a "Made in Italy" sticker on it. However, Gastone Rinaldi made a collection of chrome chairs but this Etsy listing is the only thing tying Rinaldi to this chair. I cant find any more information on the chair. Anyone here that can confirm that this is Rinaldi? Is there a good archive online of designers and their collections any design addict should be aware of? 🙂
