But I think that by the time the SIS stuff was being produced a lot of the design and production had changed dramatically.
Shhh I have a long cage 600 (non SIS) just like the one in the picture, waiting for a build I'm working on. The donor bike had the full group minus the shifters which are Suntour Accushift. My crank is a 600 triple, so it will be a touring rig. Can't wait to see how it shifts.
I never had an Arabesque setup but I had a Golden Arrow back in the day which seemed to work fine. Surely the Arabesque worked as well.
