This manual didn’t belong to either of my uncles who served in the Navy, but I was certainly glad to find a copy. Delbert and Donald Wilson enlisted in the US Navy in 1934. Donald stayed in, but Delbert got out after the original enlistment.
After Pearl Harbor was attacked, Del reenlisted.
E 1/c Delbert G. Wilson served aboard the USS Maumee (AO-2) during the war; also worked an Attack Teacher at the US Naval Submarine School.
CEM Donald W. Wilson was already on the crew of the USS Yorktown, which was sunk at the Battle of Midway. Surviving electricians helped bake out engines on the USS California (BB-44), which had been raised after being sunk during the Pearl Harbor attack. Then served on the crew of the USS Yorktown (CV-19)
