Thanks T-Mar for the clarification on 600EX vis a vis 600 Arabesque. Although my photo of the RD reveals a plain design, unlike your photo, the underside of the shift levers (which I didn't photograph) do have some curly, baroque style flourishes. Is this moot or perhaps I've got a mongrel combo? I'll take some more photos.
