Dal I may be wrong but some gun made before 1968 didnt have to have a serial number on it. I have taken my Chuckster apart and cant find numbers on it anywhere. Thats why I ask if anyone knew when the gun was produced. I also have a J C Higgins .22 Dad bought from Sears sometime in the 50's that doesnt have any on it. The gun was made by High Standard for Sears. Guess they just have to be old.
