The wreck which was supposidely the Cyclops was never found again and hasn't been relocated to this day. It was said to have been broken in two near the stern, with the stern lying on its side. This has since been assumed to have been a structural weakness in the class.
Thanks for the pictures of the Nereus. The Proteus actually had a different bridge than that - I guess most members of the class looked different from each other.
BTW - GREAT HOSPITAL SHIP SERGBUTO!
