Dating German 22 boxes

Has anyone out there figured out how to accurately date German 22 rifle boxes?

For example, when was this one made?

Thanks,
Dave

Dave–Go to the following, then scroll down to Germany.

In the Germany update look for RWS-3-S-3 on page 66.

A great reference that I was not aware of!

Thank you!

Dave
