SECTION I TM 5-3810-232-34P f. QTY (Column (6)).  The QTY (quantity per figure column)  indicates  the  quantity  of  the  Hem  used  in  the breakout   shown   on   the   illustration   figure,   which   is prepared for a  functional  group,  subfunctional  group,  or an assembly.  A "V" appearing in this column in lieu of a quantity  indicates  that  the  quantity  is  variable  and  the quantity may vary from application to application. 4.  Explanation of Columns (Section IV). a. 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.) When using NIIN 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 III. (3) ITEM column.  The item number identifies the item associated with the figure listed in the adjacent FIG.    column.    This  Hem  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.) (1) FSCM column.  The Federal Supply Code for Manufacturer (FSCM) is a 5 digit numeric code used to  identify  the  manufacturer,  distributor,  or  Government agency, etc., that supplies the item. (2) PART   NUMBER   column.      Indicates   the primary  number  used  by  the  manufacturer  (individual, firm, corporation, or Government activity), which controls the design and characteristics of the item by means of its engineering    drawings,    specifications    standards,    and inspection  requirements  to  identify  an  item  or  range  of items. (3) STOCK  NUMBER  column.    This  column lists   the   NSN   for   the   associated   part   number   and manufacturer   identified   in   the   PART   NUMBER   and FSCM columns to the left. (4) FIG.      column.      This   column   lists   the number of the figure where the item is identified/located in Section 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. (1) FIG.  column.    This  column  lists  the  number  of the figure where the item is identified/located in Section II and III. (2) ITEM  column.    The  Hem  number  is  that number assigned to the item as it appears in the figure referenced in the adjacent figure number column. (3) STOCK  NUMBER  column.    This  column lists the NSN for the Hem. (4) FSCM column.  The Federal Supply Code for Manufacturer (FSCM) is a 5-digit numeric code used to  identify  the  manufacturer,  distributor,  or  Government agency, etc., that supplies the item. (5) PART   NUMBER   column.      Indicates   the primary  number  used  by  the  manufacturer  (individual, firm, corporation, or Government activity), which controls the design and characteristics of the item by means of its engineering    drawings,    specifications    standards,    and inspection  requirements  to  identify  an  Hem  or  range  of items. 5.  Special Information. Use the following subparagraphs as applicable: a. USABLE   ON   CODE.      The   useable   on   code appears in the lower left corner of the Description column heading.  Usable on codes are shown as " UOC .      ." in the  Description  Column  (justified  left)  on  the  first  line applicable    item    description/nomenclature.        Uncoded items  are  applicable  to  all  models.    Identification  of  the useable on codes used in the RPSTL are: BGJ Model2380 BGH Model 2385. b. FABRICATION INSTRUCTIONS.  Bulk materials required   to   manufacture   items   are   listed   in   the   Bulk Material Functional Group of this RPSTL.  Part numbers for bulk materials are also referenced in the description column   of   the   line   item   entry   for   the   item   to   be manufactured/fabricated. Detailed fabrication instructions for items source  coded  to  be  manufactured or fabricated are found in TM 5-3810-232-12 and TM 5- 3810-232-34. c. ASSEMBLYINSTRUCTION.    Detailed  assembly instructions  for   items   source   coded   to   be   assembled from  component  spare/repair  parts  are  found  in  TM  5- 3810-232-12 and TM 5-3810-232-34.  Items that 4
