Can you identify this boat dock bumper?

Found these “boat dock bumpers” at an auction.  Plan on fixing up the dock, would need to order more bumpers.

 

Who makes these bumpers and how are they intended to work?

Just from looking at them I would not think they were dock bumpers.

 

It appears, from that little square hook it has, that they are designed to hook over the gunwhale of the boat.

That makes more sense.  I thought those were to bepost mounted on a 2x4.  

 

They could be pontoon connectors for party cove with the lower black  hook.  Hook to the side of your pontoon, the white could fold down to hook the gunnel of the next boat.  Making a SxS chain.

Perhaps similar to these, but with the added "hook" that would lap over the pictured board:
