My current stallions are just yearlings, going to be two year olds in 2006, but two of them look to be B size when they are finished growing.
This is Magic Mist Raging FireNSmoke ("Rage"). His sire is a Seth Thomas horse, ASPC/AMHR, 34", and his dam is my prolific mare Wild Winds Frost Fire who is 35". I expect Rage to mature right around 35". Here is a weanling pic of him
and a yearling pic (I need better pics of my boy!)
My other B size future stallion is CCMF Spotted Illusion. He was supposed to stay under, but it is not to be. He's so gorgeous though and such a sweet boy, lucky for both him and me that I have a use for B stallions.
I think he will mature about 36"
And my post wouldn't be complete without the stallion that we lost earlier this year, the stallion I owned in partnership. NJ's Almost A Spot, Halter Hall Of Fame, Reserve National Champion, All Star Champion. I have only one foal by him, that I treasure with all my heart. "Spot" was about 35 1/2". Rest in peace sweet boy.
