She was served once to Afleetaffair in 2005 which means the foal would have just turned three. You will need to contact the breeder/owner of the mare Mr B and Mrs S Denham.
Tto do that you will have to contact the stud book.
The contact is
jstewart@ajc.org.au they are really helpful and will help you sort it out. The horse will need to be DNA tested which is included in the $300. PM me if you would like more help. She is no longer being used as an asb broodmare and has been dropped from record.
Good Luck
