Caterpillar turbo PN#6N8221 will mount and operate on a C.Cat engine need to know if caterpillar turbo PN#2360587 Garrett PN#726692-12 or caterpillar turbo PN#6N8221 will mount and operate on a C-15 550 Cat engine.

Below is the download link for a special resource for dating Winchester firearms. These pages were scanned from documents compiled over the years by the customer service department of Winchester Repeating Arms. None of the page scans are of original documents but are simply transcribed information typed into a word processing program. In general, this information is the same that you would get if you called our customer service department and asked them for the information. They use these documents as a reference and the documents should be limited to that use.

THE HISTORY OF WINCHESTER HISTORIC SERIAL NUMBER RECORDS.
There are many “legends” about why the historic serial number records for Winchester rifles and shotguns are not complete or why they are not always verifiable. A few reasons cited are:

1. A fire at the factory
2. Inadvertent destruction (during office cleaning)
3. Records simply lost in filing
4. Records misplaced between ownership transitions
5. Documents borrowed but not returned

There is probably some kernel of truth to all of them. But the fact remains; there is no original, single, totally accurate database of serial numbers from 1866 forward that we are aware of. But perhaps these pages can help you somewhat in your research.

Please keep the following points in mind as you explore these pages:

• Many of the Winchester brand firearms produced over the years are included, but not all. If your firearm is not listed, we probably do not have any additional information.
• Before the 1990s the Winchester Repeating Arms firearms brand transferred ownership several times. Any information before the 1990s is always difficult to verify.
• In general, only serial number ranges with an approximate year are provided in this document. There is no other detail beyond this that we can provide.
• Since this information was provided through old documents (both official and otherwise), no representation is made that all serial number and year combinations are totally accurate.
• In some exceptional cases, a more detailed, accurate determination can be made by calling the Winchester Repeating Arms Historian at the Morgan, Utah office. 800-333-3288. Ask for the Winchester Repeating Arms Historian.
• For any other questions: 800.333.3288 or 801.876.2711. For Parts and Service call: 800.322.4626
• For questions related to Ammunition don’t call us. Contact Winchester Ammunition directly.
• No attempt has been made to determine the value of any guns listed.
• The Cody Firearms Museum has more information on Winchesters produced before 1900.
• This late historian George Madis compiled extensive histories on Winchester firearms. www.georgemadis.com

Example: An error of one year for a Caterpillar 320CL Excavator, serial number PAB04968, changes the value by $7,759:

*Notes: Year of manufacture data sourced from Top Bid’s Serial Number Guide and a competitor’s guide. Value data sourced from one year of auction results based on Top Bid’s Price Reference Guide.

Validate the year of manufacture to ensure a reliable value. Avoid paying too much for used construction equipment or not asking enough when selling your current equipment. An error of just one model year (2005 vs. 2006, for example) can change the price by thousands of dollars.

The Serial Number Guide is the leading source for year-of-manufacture data on all major and hard-to-find construction equipment. This means you get over 50 years of serial number information from more than 585 manufacturers representing over 100 equipment types in construction, forestry, paving, material handling and aggregate industries – FAST! The guide also includes over 15,000 models with shipping dimensions. The Serial Number Guide is available in three formats:

Also, an extraordinary effort has been made to verify, categorize and interpret serial number data from several million records of UCC filings. The use of this exclusive source of information makes this Serial Number Guide the most comprehensive resource available. The format of the Serial Number Guide follows the standard practice of listing serial numbers either by a machine’s make and model (and in some cases, Caterpillar being one, by serial number prefix) or by its manufacturer only when one set of numbers covers all categories and all models in a product line. Numbers are listed lowest to highest for known numbers assigned to machines in each given year. In some cases, because of the system a manufacturer may use to assign numbers, it is necessary to assign an arbitrary cutoff to the range of numbers for a given year. In these cases our team of analysts uses UCC filings to determine the most accurate cutoff points possible.

There are many manufacturers of equipment, past and present, that embed codes or use unique combinations of numbers in particular places in the serial number string to designate the year of manufacture. Examples of these may be the use of a letter to indicate a year (e.g. A = 1987, B = 1988, etc.) or several digits to note a month and year (e.g. 1092 = October 1992). Top Bid’s staff has gone to great lengths to contact manufacturers and verify their codes and formats. The notes shown for these manufacturers will clearly explain how to interpret serial numbers. Many manufacturers in this Serial Number Guide are no longer in business and therefore cannot be contacted. Top Bid relies on the experience and judgment of its analysts and other professionals in the business to verify information long in the public domain.
