titleist pro v1 392

How do I check the year of a Wilson ball?
I found a Titleist Pro V1 ball. How can I identify what year was it made? I understand that the arrows around the "Pro V1 – 392" text are different for each year. Is there a guide that shows the marks of each year and that can identify this ball? Thank you.
and new others say the number of dimples in them, what is the model of 07 because it is the only other model arrows
