I don't know about every brand, but according to Berkley you can decipher their
code easily. It's located below the bar code on the spool and will look
something like this: L-21-2-1. The translation is as follows: L = December (A =
January, B = February, C = March, etc..), 21 = 21st day of the month, 2 = 2002
(3 = 2003, etc..), 1 = 1st run on that date. So L-21-2-1 was made in the first
run on December 21st, 2002. I hope this helps.
