Can anyone tell me about a warm blood stallion Red Boy Z?

Info on Red Boy Z by Artos Z warmblood stAllion and a mare mamsetta by Silver Baron?

That he appears to exist only on all-breed pedigree with half the pedigree missing?? And also on all breed as the sire of a 2005 mare who does compete in low level jumpers in Virginia, also with the seemingly unwarranted z suffix.

Thank you

Do you know anything about a mare named Matadora? Produced alot of jumpers?

You should probably post this over on the Sporthorse breeder’s part of the forum.
