I have for sale an Unbreakable Stainless Steel Uno-Vac Thermos.
This is a vintage Uno-Vac stainless steel thermos, 5 cup/40 oz capacity, made in the USA by Union Manufacturing Co. It is 13" tall including the cap. It's in good shape with light cosmetic wear such as a small ding here, a light scuff there. Stopper and cup/cap are both present. The inside looks very clean.
