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 numbers 0 through 9 and each following letter or digit in like order).
(1) CAGEC Column. The Commercial and Government Entity Code (CAGEC) 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 engi-
neering 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 manufac-
turer 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 Sec-
tions 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.
5. Special Information.

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 item source codes to be
manufactured or fabricated are found in TM 9-2350-311 -20-2 and TM 9-2350-311-34-2.
c. ASSEMBLY INSTRUCTION. Detailed assembly instructions for items source coded to be assembled from
component spare/repair parts are found in TM 9-2350-31120-2 and TM 9-2350-311 -34-2. 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 at the end of the associated parts list.
e. INDEX NUMBERS. Items which have the word BULK in the figure column will have an index number shown
in the item number column. This index number is a cross-reference between the National Stock Number/Part Number
