There are a number of catalogs published by the Eastman Kodak Company that lists the NSNs of imaging equipment and materials that are on the GSA schedule. One publication that may be useful to you, as a supply petty officer, is the Commodity Oriented Procurement System (Electronic Data Interchange). This publication is commonly referred to as COPS or EDI.

COPS is a catalog for Kodak photographic products and other items that are available through DGSC, Richmond, Virginia. COPS/EDI is a computer-tocomputer system. To use the system, you must first fill out a requisition. The requisition must then be sent to base supply or your supply department. The order must then be transmitted to DGSC. DGSC transmits your order by computer to computers at various Kodak Regional Distribution Centers. The order is sent directly to your activity in 5 days for factory-stocked items and 30-45 days for special orders.

NAVY STOCK LIST OF PUBLICATIONS AND FORMS

The Navy Stock List of Publications and Forms, NAVSUP P-2002, commonly referred to as the "I Cog Catalog," consists of three sections as follows:

Section I-Alphabetic/Numeric Listing of Form Numbers, Publications, Hull Numbers, Electronic Model Numbers, and Standard Subject Identification Codes for Cog lI Forms.

Section II-Alphabetic Listing of Publications and Forms by Title/Nomenclature.

Section III-Numeric Listing of Publications and Form Stock Numbers followed by technical directives (by type and directive number). Publications and Forms are sequenced together. Microfiche editions of NAVSUP P-2002 are issued quarterly; each edition reflects all current Cog 01 and lI Publications and Forms. Section I and section III reflect information, such as "Canceled," "No Superseding Item," "Superseded By," and "Replaced By."

The Introduction to Navy Stock List of Publications and Form provides detailed information about the columnar arrangement of the stock list. Additionally, it provides the instructions for requisitioning publications and forms.

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 CrossReference 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.

Drawing Number

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.

Drawing numbers may be used to identify microfilm that may be available on the equipment or assembly. Some large assemblies are illustrated in IPBs but are not broken down sufficiently to show identifying data for their component parts. By obtaining the drawing number of the larger item and cross-referencing it to the applicable microfilm, you can obtain sufficient identifying information for the component part.

Specification Number

A specification number is assigned to documents describing the characteristics and properties of material purchased by the Federal Government. These specifications are used by purchasing officers to ensure that all of the requirements for the material are met. Specification numbers on some support equipment are particularly useful when you are trying to procure component parts.

Nameplate

Some equipment has a nameplate attached that provides such information as the manufacturer's name or code, make or model number, serial number, size, voltage, phase, NSN, and so on. This information is particularly helpful when you are requesting material that is not subject to the Federal Catalog System. MANUFACTURERS'

INSTRUCTION BOOKS

Most equipment purchased for Navy imaging has with it an instruction book or a technical manual that is published by the manufacturer. You can often use it to help you identify specific parts, since this technical manual often includes parts lists, detailed drawings, and specifications.
