Take an in-depth look at the Spitfire’s Gun Sight Mark 2. We shall look at the Reflector and the Projector Mk.I units. We shall also look at the Gravity Drop, Harmonization of the guns and Deflection Angles. I shall refer to the 1942 Air Ministry Manuals and show my relevant re-worked colour AP diagrams.
