The Glenfield Marlin Model 30, often referred to as the Model 30G, was produced starting in the late 1970s. The serial number can help date the specific firearm, as Marlin used a consistent numbering system. However, without the actual serial number, it's not possible to determine the exact year of manufacture. Typically, you can refer to Marlin's serial number lookup charts for more precise dating.
