Found this on a coastal defence site.  Markings suggest it fitted a Mk VII 6 inch gun.  I am interested to know exactly how these discs were fitted and connected to the sight mechanism. Can anyone help with technical or diagrammatic details. I suspect from the little info I could find on them that they had a short use life as when new shells were developed a new disc with appropriate calibrations had to be fitted to the gun. 
Cheers
