This is a stripped down Pilots Display Unit Chassis with the lower part of the Optical Module attached. The missing exit lens assembly (see C0986) allows a fairly unobstructed view of the internal elements of this type of HUD optics.
It is fitted with two controls: (A) scrolls an attenuating blind across the optical path to reduce the display's brightness for night use and (B) depresses the angle of the stand-by sight reticle (this is a vertical scale that forms a very basic backup to the electronic display).
The two flexible pipes (C) either side of the fold-mirror (D) are fibre-optic bundles that feed light from a light source (E) to the standby reticle image blocks (F), one on each side of the injection optics (G). Rotating the depression control (B) raises or lowers both these blocks (F) via the shafts and gears that can be seen.
