Used to have a light alloy box with lid out of a Vulcan PSP kit. It had a wire handle that clipped on top so you could use it as a food cooking / eating container as well as cup/collect berries in, etc, etc. Box measured 9″x 5″x 2+” approx. Might still be kicking around in attic. probably full of old RAF bric-a-brac. Got it from a time ex-kit during my stint at Goose Bay in early 1970’s.
