gun layer's and turret train opera tor's compartments to connect
to eleva tion indicators and the turret train opera tor's
handwheel bracket respectively. The couplings connecting these
shafts to the elevation indicators and turret train operator's
handwheel bracket are the extent of the mechanism covered in
the sight design.

10. , The component parts of the sights are shown on general
arrangement drawings number 231150-231176, 232423, 232424.
The main divisions are pointer IS S ta tion and trainer I s station
with all parts associa ted bearing this designation. Other parts
are known by the sight function transmitted as: sight angle,
elevation order, sight deflection, and train order. In the
description that follows the components have been grouped under
the heading of pointerls station; trainerls station; turret
train order selector clutch; elevation order, train order,
and sight angle shaft, gear br ackets , and bearing brackets;
sight hood assemblies; and sight setter's clutch warning circui
t , Separate paragraphs also deal with the sight setter I s
warning circuit, telescope Mark 66, sight setterls indicators

11. The right and left pointers I and trainers I stations
being of opposite hand, but otherwise identical~ the description
of one applies equally to the like parts of the other
station.
