Year of Manufacture information made available by Winchester Customer Service Dept.
The Winchester Repeating Arms Customer Service Department has now made certain compilations of information on serial numbers and year of manufacture available online at winchesterguns.com. Although not complete or defiinative, the entire team hopes this information will help in doing basic research on many Winchester firearms made since 1866 through the early 1990s.
Winchester Firearms Manufacturing Dates by Serial Number and Year
1866 through the early 1990s
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.
A FEW NOTES ON 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:
A fire at the factory
Inadvertent destruction (during office cleaning)
Records simply lost in filing
Records misplaced between ownership transitions
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.
