(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. (4) FIG.        column.        This    column    lists    the number of the figure where the item is identified/located in Sections II and III. (5) ITEM  column.    The  item  number  is  that number  assigned  to  the  item  as  it  appears  in  the  figure referenced in the adjacent figure number column. c. FIGURE AND ITEM NUMBER INDEX.

(3) STOCK  NUMBER  column.    This  column lists the NSN for the item. (4) CAGEC   column.      The   Commercial   and Government    Entity    (CAGE)    Code    (C)    is    a    5-digit alphanumeric  code  used  to  identify  the manufacturer, distributor, or Government agency, etc., that supplies the item.
