NATIONAL STOCK NUMBER (NSN) INDEX. (1) STOCK   NUMBER   column.      This   column lists   the   NSN   by   National   item   identification   number (NIIN) sequence.  The NIIN consists of the last nine NSN digits of the NSN (i.e., 5305-01-674-1467) NIIN When using this column to locate an item, ignore the first 4 digits of the NSN.  However, the complete NSN should be used when ordering items by stock number. (2) FIG. column.  This column lists the number of  the  Figure  where  the  item  is  identified/located.    The figures are in numerical order in Section II and Section Ill. (3) ITEM  column.    The  item  number  identifies the  item  associated  with  the  figure  listed  in  the  adjacent FIG.  column.    This  item  is  also  identified  by  the  NSN listed on the same line. b. PART  NUMBER  INDEX.    Part  numbers  in  this index are listed by part number in ascending alphanumeric   sequence   (i.e.,   vertical   arrangement   of letter   and   number   combination   which   places   the   first letter or digit of each group in order A through Z, followed by  the  numbers  0  through  9  and  each  following  letter  or digit in like order.)

(3) STOCK   NUMBER   column.      This   column lists    the    NSN    for    the    associated    part    number    and manufacturer    identified    in    the    PART    NUMBER    and CAGEC columns to the left.
