This is the last info I have gathered from the forums:

Old chart of Brunswick Serial Number codes.

First letter is the month.
A - Jan. B - Feb. C - Mar. D - April E - May F - June
G - July H - Aug. I - Sept. J - Oct. K - Nov. L - Dec.

Second letter is the year
F - 1992 G - 1993 H - 1994 I - 1995 J - 1996 K - 1997 L - 1998 M - 1999 N - 2000
O - 2001 P - 2002 R - 2003 S - 2004 T - 2005 Y - 2006 Z - 2007 A - 2008

But now this has changed since they moved to Mexico.


Storm/Rotogrip, the year is the first two, followed by a three letter code for the ball
Followed by a batch code, then a ball serial number (the specific ball in the batch)

Thanks. I should have clarified that my Brunswick and Radical equipment that I've purchased this year uses the alpha to start the serial number string.
