English: Labeled diagram of an unknown version of the Course Setting Bomb Sight, also known as a Wimperis sight. The large airspeed dial at the rear of the device suggests this was a pre-war model, as the Mk. VII and Mk. IX versions used in most combat aircraft during the war moved the airspeed dial to the right side of the sight. It does feature a trail setting on the right, which means it is a Mk. II or later. But it is lacking the large levelling screw on the left side of the sight, part of the Mk. II. In this example the levelling system has been replaced by the flexible levelling mounting (lightly coloured in this image). This combination of features suggest it is likely a Mk. V or VI. The image shows the bombsight mounted in the bottom of an aircraft, which strongly suggests this is a Fairey Battle, which had a roughly teardrop-shaped window in the floor of the aircraft under the wing area.
