Help identify Roller furling system

I have a roller furling system that uses a hanked on jib. There is a swivel attached to the top and bottom of the stay. Instead of a foil the stay turns as you furl the jib. Works great except when you want to shorten your sail area.

It sounds a bit like the old Schaeffer furling system with a jib on a wire luff and a two part furler: swivel on top and a drum on the bottom. I'm not sure about yours.
