SECTION I TM5-3810-294-20P f. OTY (Column (6)). The QTY (quantity per figure column) indicates the quantity of the item used in the breakout shown on the  fl1ustration 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 I 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 IIl. (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.) (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 item 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 item. (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 item or range of items. 5. Special Information. Use the following subparagraphs as applicable: a. USABLE ON CODE. Not Applicable. 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- 294-20. c.. ASSEMBLY INSTRUCTION. Detailed assembly  instructions  for  items  source  coded  to  be assembled   from   component   spare/repair   parts   are found in TM 5-3810-294-20 . Items that make up the assembly     are     listed     immediately     following     the assembly   item   entry   or   reference   is   made   to   an applicable figure. d. KITS. Line item entries for repair parts kits appear in group 9401 in Section II. e. INDEX NUMBERS. Items which have the word BULK   in   the   figure   column   will   have   and   index number shown in the item number column. This index number 4 SECTION I is a cross-reference between the National Stock Number/Part Number Index and the bulk material list in Section II.
