MANUFACTURERS' PART NUMBERS
When replacement parts are needed, either to repair
equipment or for ready spares, you usually must know
the part number assigned by the manufacturer.
Normally, the manufacturer affixes a part number
on each item manufactured. This part number, coupled
with knowledge of application and usage, leads to the
nomenclature and National Stock Number (NSN) of the
part. The part number can be verified by referencing it
to the appropriate Illustrated Parts Breakdown (IPB).
The NSN may be obtained by referencing apart number
to the appropriate Consolidated Master Cross-
Reference List (C-MCRL). You should remember that
part numbers may be duplicated by various
manufacturers; therefore, the Federal Supply Code
(FSC) for manufacturers must be considered when
cross-referencing a part number to an NSN.
A drawing number consists of letters or numbers,
or a combination of letters and numbers, that are
assigned to a particular drawing for identification
purposes. The activity controlling the drawing
(normally the manufacturer) assigns the number
conforming to their drawing numbering system. One
drawing may apply to several items; thus other
distinguishing information is required to identify the
item on the drawing.
