A-W The largest gun now mounted
on a destroyer is five inch. (2) A six
Sights are set by turning small knob
which is attached to wheel-like instru-
ment. q talked to a former officer in the
Navy and he tells me that this wheel-like
instrument is calibrated somewhat in the
form of a vernier). (4) The sight setter
usually stands while setting sights. My
informer stated that in the larger guns
there is large platform which revolves
on an axis along with the gun while with
smaller guns the man stands so as to get
around more easily, although in some types
of guns the sight setter sits on seat
similar to the seat on mower or binder.
We were pleased to secure this information
for you from the Local Recruiting Station

gave me the impression that he had re-
Gently been On board ship and was con-
