Items listed in this publication, which are source coded XA or XB, may have been
subsequently assigned an NSN because of other applications in the Marine Corps.
Therefore, if an item source coded in the XA or XB series in this publication is
required, users are directed to first make the following investigations:
Check the corresponding part number in the Master Cross-Reference List
(C-RL), to determine if an NSN has been assigned.
If an NSN has been obtained from the above check, refer to the Management
Data List (MDL) for the latest supply management decision regarding the
Check stock for availability of part/parts having National Stock Number.
If the review of stock discloses that materiel is not available, refer to
the MDL for inventory record data regarding the preferred NSN which may
have been obtained in the Master Cross-Reference List (C-RL) and Manage-
ment Data List (MDL) review.
Prepare a requisition citing the stock number shown in the Management
Data List (MDL).
The above review will assist the user in obtaining the correct item of supply
from the supply system, when available, rather than through alternate methods
such as obtaining the desired part from salvage, requisitioning the next higher
assembly, or recommending that the equipment be overhauled or retired. If a
stock number for the desired item does not exist, then the source of supply as
definined below will prevail:
Applied to items not maintained in the supply system; replacement of these parts is
neither practical or economical. Support of the end equipment will be effected by
replacing the next higher assembly.
Applied to items not procured for stock, but may be acquired for use through salvage.
Activities requiring such items will attempt to obtain them from salvage; if not
obtainable from salvage, such items will be requisitioned through normal supply
channels citing manufacturer's code and part number with supporting justification.
Applied to installation drawing, diagram, instruction sheet or field service drawing
identified by a manufacturer's part number.
