A lot of our early rifles do not have serial numbers. Before 1968 it was not mandatory for us to use serial numbers. To check the rifles manufacturing date, we would use the barrel code. The barrel code is a series of 2-3 letters found on the barrel close to the receiver, on the left hand side. If you contact us at 1-800-243-9700 or firstname.lastname@example.org with the model of your firearm and 2-3 barrel code, we can determine the date of manufacture.
