I’ve never seen a Eureka Tote Tray like that! Probably made out of cardboard. Though offers an easier way to store the tools by just dropping them in the box, it may take up too much room on the floor or shelf of a closet. Would love to a see a pic of a real one!
It looks like the colour of the canister is charcoal gray. Never saw a 1960’s Eureka canister in that colour!
