vintage aluminum picnic & camping thermos, 50s-60s insulated cooler jug

1950s or 60s vintage picnic or camping thermos, fiberglass insulated aluminum. This is a Feather Flite, made by Prolon, 2 or 2 1/2 gallon size, I think. The exterior of the bottle measures about 10" x 10".

There's some fading to the red plastic lid, but overall this looks pretty good, inside and out.
