Can you get more pictures? does it have a Part Number? Navy loves its brass thingies, and even more so they LOVE putting Serial Numbers on brass thingies, cause brass thingies is worth real money!
It's the fire control gimble mechanism for a Close In Weapon System CIWS, probably the MK-92 anti inner-tube destruction device (ITDD), it's probably an antique by now. Rancher
With up to three others showering in close proximity to that thing, no way I'd be dropping the soap....thank goodness for soap on a rope...
A friend of mine who spent time in the Navy told me he used to drop powdered soap - takes longer to pick it up.
Looks like an engineering officer's brass paper weight. How come that damn steward didn't polish the damned thing like I told him to? Now I am going to have him flailed with a cat o nine tails
I think she has decided its a nautical transit base, Upside down and missing the top half with the sight level
That explains the chain in the center to hang a plumb bob. That, of course, rules out shipboard use. Possible CB use.
If memory serves, it being brass was acceptable payment to Suzy's side cleaners in exchange for a pint of rum. Lowered to their boat on a length of small stuff and when you retrieved the line a pint of rum was attached. Transaction best done from the fantail and in low light conditions.................that's the story I heard.......from some sailor somewhere.
So, i just asked the Cptn, and he says it may ( may) be a part of the ships compass, particularly a secondary, or back up compass and the chain would be used to secure it from slidin off or tipping and spilling a very expensive compass! Most ships in the era this came from would have had a steam driven gyro stabilised compass, so it would have to have been very sturdy, which this looks like!
