I looked on equibase and apparently he was owned by Winky Yang (what a fantastic name!) and trained by Daniel Leung - if you so wanted to you could try and contact the trainer directly and see if he can enlighten you any. Many trainers are more than happy to give you a bit of background and many will have old winners photos... although of course there are some who really can't be bothered but you don't know until you try. It should be easy enough to find a contact number for the trainer. I can't envision the racetrack itself being any help as they wouldnt really keep any records other than results.
Best of luck!
Stop for a minute, open your mind, learn. You may not agree with what I say, I may not agree with what you say but we will both learn something new.
