What year was your Model 1907 made?
Where the serial number is
Two places on the left side: on the lower frame and upper receiver, just above the trigger.
Where these dates come from
Winchester's original factory records do not cover every model. For the Model 1907, the dates come from one published source, George Madis's published tables. It was typed up long after production, so treat any year as a close estimate rather than a factory record.

Want proof on paper? Order a factory letter
The Cody Firearms Museum holds Winchester’s original records and, for a fee, will search them for your serial number and send you a letter with the recorded dates and details. It is the closest thing to the original factory entry you can own, and it is what auction houses and appraisers accept.
Its records cover Model 1907 serial numbers: 1–50,000. A number outside that coverage cannot be lettered.
