need help with an aus brand

So my friends working with this thoroughbred has no info on his history and wants to find out. They are 99 percent sure that he's an ex race horse and he's apparently big. Heres the info I've been given to look for him on the stud book.
TB chestnut, 1 white sock on nearside hind leg, white blaze, brand on offside 102 over 2


Heres a picture of the other brand.
Does anyone have any knowledge of how I can find out who he is or what stud he came from in Australia.

Call the Stud Book. Seriously, they can and often will help. The biggest trick is figuring out what the brand is to describe it to them...

Found him, can someone please delete this entire thread thanks

how did you find the info ? I am also looking to find info , I am looking for a friend. I do know that the numbers represent that he was horse 102
Bred in 2002 or 1992.. Did you find a phone number ? Thanks for any additional info.
