Probably a wheel off the Newport News. Those things are highly desirable and pilferable by individuals leaving the command. During the 4 years I was on Ranger we had three different wheels. Especially the smaller wheels. I remember seeing sailors carrying off throttle wheels from ship's engine rooms as recently as 1999. But those ships were going through decommisioning. You never know what is going off the ship in all of those garbage bags.
Ship's bells, too. Not the big, 600 pound fog bells (although we had one stolen off the Ranger when we were in Subic Bay, PI in 1974) but the smaller ones used on the bridge and quarterdeck. I don't recall seeing any ship's bells with the ship's name or date on them for over 38 years. One reason for that is that would make them even more enticing to swipe. Maybe this practice is not as prevalent now as it was back in earlier times, but I am sure that it is common enough. They shine up really pretty.
Nevertheless, ships don't always go through their lives with all of their original equipment. And who is to say where the wheel in that case or the wheel on the current USS Newport News came from originally.
I saw two episodes of Pawn Stars where, in one, a quartermaster's long glass and, in the other, where a Navy chronometer (in the gimballed box housing and with the securing pin installed) were being pawned. I wonder where they originated. This stuff is usually recirculated in the fleet. That is one reason for the NCIS's existence.
