What are these for? (see pics)

[Bergie]

I bought a 'grab bag' of gun stuff at an auction (got ripped off, but that's beside the point). In the box of stuff were these three things I can't identify- the oil can is an obvious, but am not sure to what and from where. No markings on it. The black tube of cleaning stuff I think is AK/SKS, right? But the sling? No clue....there's a snap hook closure on one end on a D ring, then a frog and just a slide buckle on the other end. Please tell me these are all rare and expensive, because I have no need for any of it! Trade me a muskie lure or two and it's a deal....

Looks more like for a mosin-nagant. The sling is typical of that.

Common ak sling and cleaning equipment. Not for Mosin
