The plastic sleeve spins completely freely 360 degrees, but it feels vertically locked/mechanically captured and refuses to slide off the top when pulled. There are no grub screws anywhere on the casing, and applying heat with a hairdryer didn't expand it enough to budge.
I've seen a few pictures of this lens without the sleeve.

Does anyone recognise this setup and is there a trick to get it off, or should I bring out the saw?
