Interesting marketplace item

[Chevy nutcase]

Whatever algorithm Facebook uses to suggest items on marketplace sometimes is handy. This popped up and it falls into one of those quirky things that'd be cool to have. I've been trying to think where and when this would have been useful. Ok you painted your hubcap but now you have a flat spare . I tried looking it up but only ne sold example came up on ebay with no useful information. So if anyone knows what tie this would've been available and it's intended use I'd be grateful
