Hamer Serial Numbers

Does anyone know of a way to tell by the serial number (by brand) when the ball was manufactured.
My Virtual gravity starts with 09, knowing this ball was manufactured in 09 I can only assume that storm starts theirs of with the year.
I have an old White Dot and an old Super Beast though (both columbia 300) which I am not sure on both had previous owners the SB serial number starts with a 7 and from what I found online the SB started manufacturing in 1997 .. my WD starts with a 9 which makes me assume it was made in 1999... BUT
is there a place or site that lists how to read the serial codes per brand to know for sure when they were made?
Thanks
