Hi guys, new guy here. Don't know much about this stuff (car guy) but a buddy pointed me here. I have a '69 or '70 (I think)Avocado kettle, it was my dads and he was taking it to the scrapyard, he hasn't used it in 20 or more years, been sitting in his shed. I was going to see if a buddy of mine wanted it, so I saved it. I've attached some pics, what ya'll think it is worth? It has the Pat Pending on the top vent.
