Sorry, Seascouter, don't have any more pics at the moment, but my sails have a wired luff, (running in the luff edge seam and crimped loops at each end) , which are tied to the sail eyes at the head and foot of the sail with sail twine. As the drum rotates the wire twists and takes the sail with it. There is no hanking on necessary (the sail has no hanks). On larger genny's it's probably not as good as the tube type of furler that some Seahawkers use, but it works fine for the normal jib.
As the swivel is connected to the halyard direct, there is no strop and the drum (on mine) is connected to the bow fitting via a piece of s/s flat bar to bring the drum up off the deck a bit and at the same time stop the drum chassis rotating.
The following Barton Extracts might help:
