Help ID Coca-Cola cooler/ice chest year

Hi all,

My dad has given me my grandpa's old Coca-Cola cooler, one my dad grew up using on family days out and the like, and we'd love to know the actual year this is from. I've been searching online and have not been able to find the same exact model anywhere else (a couple are close, but with minor body differences, such as this one that was sold on Etsy).

Any help is appreciated - I'm sure it's 1930's-50's, but that's a pretty big range There are no identifying marks other than the logo and all you see in the image.

Ah, here you go.

"Superior Jr. picnic coolers were made in the 40's by the Sterling Manufacturing Company."
