To the maximum extent possible, the year of manufacture information was derived from the original Winchester Factory Polishing Room serialization records. However, for the models that no factory records exist, estimates were made using multiple sources of information in which case the data was extrapolated to the best of our ability. This information is no substitute for obtaining a Winchester Factory Letter from the Cody Firearms Museum (available for certain models and serial ranges) which in addition to the Serial Number Application Date, normally provides the original Received In Warehouse Date and Date Shipped from Winchester factory.
