The photo does't show the end. Is there some kind of hook on the end, or holes to screw to a wall?

Nor being able to see the end, it looks like it could be a support hook for inside a refrigerator, one of those hooks that would hold up a wire or plastic basket on the bottom or on a shelf. Here again, can't tell what the flat end looks like on the side not seen.

The other thought I had was, if the end is flat, maybe a Command Hook type attachment that holds a rod. The other hook is missing. (Kind of like a toilet paper holder mounted on the wall with adhesive tape of some sort. I did a search on different command hooks and nothing matched.)

I did Google Searches on the numbers stamped on the item, and all that keeps coming up is a Polish military hand gun.
