Can you identify this instrument

You may well be right regarding a gunnery indicator.
Now received a picture of the rear:
Clearly a remote electrical indicator, so that matches the 5T stores ref. Diameter 200mm.

Jenkins, for the benifit of us in the colonies, could you please convert your last message into English or some other form more likely to be understood in the "Great White North"? I have in the past had to use a translator to understand Glasgow Tower so have little chance of understanding Royal Navy slang, although I must admit it is most likely understood by those with a sailing background, somthing I did my best to avoid during my military service as Im subject to "projectile vomiting "after one day at sea!{ but never air sick, go figure!}

flux capacitor
What does flux capacitor mean?
The flux capacitor was the core component of Doctor Emmett Brown's time traveling DeLorean time machine and the following Jules Verne Train. Brown stated that the flux capacitor "is what makes time travel possible."

Ran the image through TinEye and nothing found like it.
Looking at the backside image I see 5 wires and they are grouped in two and 3. This is the classic Selsyn grouping for a sender and a repeater. Connect them together and apply A/C power at the sender and they are electrical lock in rotation. Move one and the other follows.
I would have to find one of my engineering books to get more details as the last time I worked with them was in the early 1980's

I got the picture by clicking the little icon of a torn paper sheet in the address bar of IE. It turns blue and I can now see the picture. I also lost the irritating message "Do you want to leave this page".

I do believe the markings on the port side have eroded away, if you zoom in you can still see faint marks that would have indicated the 70 and 80 degree positions assuming therefore both sides of the dial were equally graduated up to 180 degrees.

Given the +- 30 degree range is marked out in 1 degree divisions it suggests to me that whatever it was fitted to was likely to be frequently steady in this range. Plus the angle needed to be measured accurately and so was significant.

I am inclined to think this is a remote readout for an Anemometer, maybe from the bridge of an aircraft carrier where the ship would be positioned into wind for launching and recovering aircraft.

Just checked about 300 detailed internal pictures of the Gato class sub, USS COD SS 224 that I took during a visit to Cleveland, OH some years ago. Pentax 7 m pixel images.
Nothing that resembles the instrument under discussion. Several pictures have incline meters in them but they appear to mechanical not electrical.
My visit was to see the sub that a close friend had done 4 war patrol's on 43 ~ 45. He talked a lot about the patrols and the action during them. Shortly before I visited the sub he left us on his last patrol. Wished I could have talked to him after the visit.

Well, I think this is the first time that PPrune hasnt come up with a definative answer on somthing like this, but there has to be some clever chap who will know for sure, maybe be we should offer a reward for the correct answer?
Thus it isn't likely to be aviation related.
Looks to me like some kind of Naval synchro/repeater as suggested above.
The restricted arc is big clue and probably rules out a wind instrument. That arc is to do with aligning something that needs to be accurately positioned within 30 deg of "ahead" and less accurately on the rest of the arcs. The restricted arc implies that for some reason it cannot be placed between Red 60 and 180. Figure what that might be and we'll have an answer.
Likely to be something not mounted on the centreline but that has limited movement across it to the left like Stbd side armament on a cruiser or battleship.
A deck crane perhaps? Torpedo tube? Not something requiring much precision like a range finder for instance.
AA/high elevation gun might fit though the emphasis on the straight ahead markings doesn't seem logical there.

If anyone knows a good maritime web site maybe they would have the answer, Im damned if I can find anything in my collection of technical books which even has anything resembling it.

It is almost definitely an apparent wind gauge (missing some markings). The reason the 30-0 sections are marked in single degrees is because you can't sail much closer to the wind than 20-25 degrees, depending on what you're sailing, so you have to be quite accurate with wind tracking.
