paragraph 4).
3. Gun elevating, turret train and sight control stations
as indicated in the above comprise the following personnel
station arrangements.
Three gun layers, one for each independently
driven elevating speed gear control, are located
on the electric deck.
One gun train operator is also located on the
electric deck, adjacent to the training gear

"LocaL" control, the gun train operator is not required. From
his station this operator controls a positive clutch, permitting
handwheel control of the train speed gear to be shifted to the
sight trainer manning the controlling telescope. Local control
operating arrangements and their variations include sight station
assignments as indicated in the following description of
the sight.
