The Mossberg Model G-4 is a shotgun that was produced in the 1960s and early 1970s. To determine its specific age, you would need to check the serial number, as Mossberg typically used a coding system to indicate the year of manufacture. If you have the serial number, you can consult Mossberg's records or a reference guide for accurate dating.
