Cleaning out old stuff of my Dad's who passed away this summer - found a mailing tube from a Rambler Nash Dealer, dated 1958. Inside was a plastic case with a tag on it: "TWIN BED INSECT SCREENS - RAMBLER MODELS - ACCESSORY NUMBER 8990416"

The case contained two small screens, all rolled up. Anybody have a clue how these were used an an accessory to a Rambler Wagon?
