It is my understanding that the entire grand staircase was totally destroyed when the ship sank and ripped out the top of the ship.
I'm curious though was the stunning Electric candelabra ever found that was at the foot of the stairs on the D-deck landing? The bronze Cherub which was found was the smaller one from the aft staircase correct?
Also what happened to the Candelabra on Olympic? There doesn't seem to be any photos of it in colour or evidence online of its current location. My only guess is that it might have been removed/disposed of as they tried to modernise before the entire ship was scrapped. I did hear the entire staircase was painted Avocado green on Olympic during her later years. I also haven't been able to find anything about Olympic's cherub lamps either.
