How can you tell when a marlin 336c was made?

You can determine the manufacturing date of a Marlin 336C by checking the serial number, which is typically located on the underside of the receiver. Marlin used different serial number prefixes over the years, and you can reference a serial number chart specific to Marlin Firearms to find the corresponding year of production. Additionally, features such as the type of finish, the presence of certain markings, or the design of components may help narrow down the date of manufacture.
