Item Identification Help

I got this item years ago in a lot of equipment I purchased. Finally decided it was time to figure out what it is. Any thoughts? As can be scene in the photos, it's stamped "S & C 1953" with broadarrow then "Cat. No IA/0102". I'm assuming it's some sort of tool roll/cover but for what, I have no clue.
