Cody Firearms Records Office
The Cody Firearms Museum Records Office has rare access to select serial number records from Winchester, Marlin, and L.C. Smith. See below for more information, serial number ranges, and a video about the services offered by the Firearms Records Office.
The Records Office provides individuals with information from the original factory records based on the model and serial number of the firearm in the form of factory letters or serial number searches.

A factory letter is the official report on the information contained in the original company records which the museum holds. Letters are available to firearms museum members and non-members for a fee. Factory letters are on Winchester or Marlin letterhead and bear the seal of the Cody Firearms Museum.
Serial number searches contain the same information as factory letters, but are a quick, informal report rather than a formal document. A serial number search is an exclusive firearms member benefit which provides the data on a firearm by phone, fax, or e-mail within 24 hours of a request.
The data included in factory letters and serial number searches varies from firearm to firearm, but may contain the following information:
|Manufacturing dates||Stock and butt configuration|
|Barrel length and shape||Magazine length|

Serial Number Application (SNA) Dates
You may have heard of the “Polishing Room Books.” We refer to the information in them as the Serial Number Application (SNA) ledgers. These ledgers record the dates serial numbers were applied to firearm components at the beginning of the manufacturing process. No configuration or customer information is recorded in these ledgers. The 1866, early 1873, 1876, and Hotchkiss serial number application dates are not currently available. For some models the SNA ledgers continue beyond the serial number ranges of the warehouse ledgers which contain configuration information. There are even SNA ledgers for models which have no other records. Click here for the list of Winchester Available Serial Number Ranges.
The SNA date, when available, is included with all member serial number searches and factory letters. If you purchased a factory letter after January 1, 2007, and would like to update the letter with the SNA, please return the original letter with a check for $15. We will confirm the factory letter data, add the SNA, and send an updated letter. Contact Records Office staff with questions.
