vintage original `Castrol` vacuum flask unused.

Vintage `Castrol oil` vacuum flask with cup lid. Very old, 1 mug size.

Although listed as `used` because of its age, it has never been, however

I filled with hot water today to test. In mint condition, seems a shame to let go

and I`m sure will be collectable one day if not already.

Size 3 1/4" diameter x 7" high.
