Hi,
I recently picked up a new lathe with a couple of boxes of bits n bobs, in one of which was this.
There was another smaller one too. I don't know if the ring is part of it, but I thought I'd better include it in the photo just in case.
There is also a packet of elastic bands packaged with them, which may or may not be relevant.
It seems obvious to me that it is some sort of chuck attachment, but beyond that I'm lost.
I hope the photos are clear enough.
Many thanks,
Dan
