I think I have the same thermos. I got it for a Christmas present in the late 80's and used it for hot chocolate when duck hunting cold mornings. It is green with a metal screw-on top that is a cup. The vacuum insulated model. I was bragging to my son's friend how long it kept drinks hot. He took it on a hunt the next day and used it alongside his brand-new Yeti. By the end of the day the coffee in my Thermos was tepid, while the Yeti coffee was piping hot. I hated to admit it, but the old Thermos was no longer king of the hill.
