mystery IH bagger attachment ?
 

does anyone recognize this contraption ?
looks like IH paint and decals, says it's from a mower bagger.
I got it with a mule drive for a wide frame but I don't know how it's meant to attach and onto which deck and what all else might be missing or how it's meant to work.
curious to me that it's open on both ends of the cone...

doesn't look like it would fit up to the narrow frame deck I have here.

I have never seen one of those before. My best "guess" would be that it goes to a leaf vacuum system and that the front conic part might have a hose attached to it for an independent way of sucking up leaves while off the tractor.
