Mechanical Aid-to-Spotter
The Mechanical Aid-to-Spotter was designed by Lieutenant W. D. Kilroy to ensure that the spotting officer was watching the same target as was being fired upon by his own ship.
Mark I
The need for these instruments was envisioned in early 1916. It seems likely that supply commenced in late 1916 at the earliest.[1] The first version was deployed in 22 of the earlier dreadnoughts and battlecruisers.[2]
Mark II
This device is detailed in Manual of Gunnery for HM Fleet, Volume III, 1920.[3] Supply of these to the latest capital ships commenced in the early months of 1919,[4] and by 1920, 22 had been equipped.[5]
Mark II*
This device is detailed in Manual of Gunnery for HM Fleet, Volume III, 1920.[6] Most often mounted in light cruisers from June 1918; an installation was generally a pair mounted on each side of the fore top.[7][8]
