I found it!!! He's a registered Standardbred ex-race horse! His registered name is "Palmer Steelster" and he was born in Ontario, Canada, last registered by NorthShore Racing Stables in IL. He was last raced in 2002 and has a lifetime earnings of $121,582. I was able to find all his stats and a 5 gereration pedigree!
Great job researching!
How sad is it that he ended up a rescue. I suppose $121,582 in winnings is chump change and doesn't constitute keeping the horse.
It's a tragic fate that most race horses end up suffering but, it sounds like Palmer Steelster will be a winner once again since he's already captured your heart
I am really happy you were able to track him down
