Petploy & Noom Nakornchaisri, dead heat in the Derby 2517.
Distant: 9 furlongs , winning time : 1: 57.03.
Both horses are by Quick Wink. a top stallion at Bang Khun Tian.
Quick Wink, also has another Derby winner name James Bond in 2515.
Another top horse by this stallion name Carol Boy did not win the derby
but he was a very top class horse in the class 1.
That's all I can remember, may be somebody like Khun Peterboy
may remember more of history.
Paul.
