The Cody Firearms Museum Records Office has rare access to the 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 make and serial number of the firearm in the form of factory letters or serial number searches.
Take a quick video glance at what we do:

A factory letter is an official report on the information contained in the original company records which the museum holds and 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.
A serial number search is a members-only benefit which provides the data on a firearm by phone, fax, or e-mail. Serial number searches contain the same information as factory letters.
Factory letters and serial number searches may contain the following information on your Winchester, Marlin, or L.C. Smith:
- Warehouse date
- Type of firearm
- Barrel length and shape
- Stock and butt
- Shipping date
- Other features
Due to the high demand for this service, we limit the number of member serial number searches to four (4) per day.

Records Office Fee Schedule
Serial Number Application (SNA) Dates
You may have heard about the “Polishing Room Books.” The staff of the Cody Firearms Museum and the Records Office refer to the information in them as the Serial Number Application date (SNA) ledgers. These ledgers record the dates on which serial numbers were applied to the 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 currently not available. For some models the SNA ledgers continue beyond the serial number ranges of the warehouse ledgers which contain configuration information, even into the 1950s. There are even SNA ledgers for models which have no other records. The list of available SNA ranges is available at the Winchester Available Serial Number Ranges link above.
The SNA date, when available, will now be 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. ContactRecords Office staff with additional questions.
